## Step 2: 2 Analysis on the Drawing

Waterfall, 1961, M. C. Escher

Waterfall, by M. C. Escher, with the delicate structure of a Penrose triangle creating the visual paradox, has been winning admire all over the world. First of all, take a close look at it....
A dimensional geometry merged from 3 hexahedrons is placed on the top of the Left Tower. And on the top of the Right Tower placed another dimensional geometry merged from 3 octahedrons. And we call the part under the waterwheel the Pool，and from the Pool there is the "1st flume", the "2nd flume" and so on. Water falls from the Platform in the upper part of the Left tower.

As the aim of this project is to re-establish the marvelous scene of Waterfall from plane to 3D and present us a vivid show, it is important that: first, how to realize the impossible architecture structure; second, how to realize the water circulation within flume-waterfall circle.
There are many different ways to approach the aim and here is just one of them. You may keep on your own probing and come up with some cool ideas~

And before the project starts, you have to convince yourself that:
1. Perpetual motion is impossible;
2. Perpetual motion is impossible;
3. Perpetual motion is impossible;

Well....and still you have to accept that:
1. Water always flows to a lower place;
2. Seeing is not always believing.

<p>Well correct me if I am wrong but since this is assisted by gravity that is not really perpetual motion is it? That aside this looks great!</p>
Good, good
This is a good optical illusion :)
<p>Excellent website on perpetual motion machines: http://www.nathancoppedge.com/Perpetual_Motion.html</p>
Masterful work. Frelling awsome!
Need someone to contribute English subtitles~
you don't need subtitles. it's not important. just some jokes, and if you don't know much about modern Chinese literature, you may miss a lot.
Several years later, Chinese will be as mandatory for every modern citizens as English : )
+1!!!!!!!!!<br>i'm weak in english
Well correct me if I am wrong but since this is assisted by gravity that is not really perpetual motion is it? That aside this looks great!
perpetual= something that is onlly given fuel 1 time but goes on untill you stop it
Actually gravity by itself would not&nbsp;disqualify a perpetual motion machine.. But as I have mentioned, this Instructible is not an attempt to create&nbsp;a perpetual motion machine, but rather&nbsp;gives instruction&nbsp;to build a&nbsp;grand (IMHO)&nbsp;illusion of a perpetual motion machine!
thanks for all those explanation. This project is indeed a piece of artwork, not a real perpetual motion machine ( if it is one, nobody would upload that on instructables, but will put that into manufacturing and make profit/ make a better world.
Amazing work/creating
Stunning work! Your attention to detail is superb. Do you have plans to recreate any other 2D illusions in 3D?<br><br>It would be interesting to see a shot of the model from the &quot;perfect&quot; viewing angle followed by a shift of the angle to reveal the fakery.

thas hella dope
Wow, great work! absolutely amazing!
bravo! Absolutely brilliant!
Wow! Congrats!
The time and effort input is unbelievable - excellent work! <br>You put in life what was only a drawing.
incredible
It seems cool~
What a incredible work!
Gelivable~~~!!!
Impressive&hellip;Gelivable&hellip;O(&cap;_&cap;)O
very impressive
Incredible. Keep it up!
Dear My Guokr!!<br>You are always creating miracles!
<em><strong>To: GuokrDIY:</strong></em> <em>YES! my friend</em> :) <strong>a Housing Camp of 400 Asian ppl is very close by where i'm living.. most of them are seeking part time job from 5pm to 11 pm.. i can hire 20, or 30 of them to produce this artwork commercially, but a &quot;production LINE&quot; procedure should be planed very accurately in a smart manner. and since you DID IT, i want to talk with u about some important points (with reserving your rights to ask me in return a whatever i may be able to pay or trade your service back for you).. 1st easy step for NOW is to reply to me (to my InBox) your email / or phone number. again..Thanks a lot my dear friend, i'll be awaiting for the respond.. </strong>
Exelent work, awesome. <br>
This piece of illusion art <strong><em>ROCKS</em></strong>. it made my day to go Pro /w instructables dot com ;) but for now here is a small question.. * <strong>Who may -please- estimate the price of material cost</strong>? (<em>in details</em>).. <strong>TY..ALL</strong>
not too much, actually. In China it costs less than 300RMB, which is about 43\$. But the time and energy actually costs a lot, if you hire someone to do that for you.
I am really impressed. WOW. I knew it had to be an illusion, but it made my jaw drop anyway. I can't believe the detail! It must have taken a long time to complete. I wonder how many people worked on it. WOW. This is the most impressive instructable I have seen in a long time. Applause.
three of us working together for a month to finally make that.
Wow GREAT illusion and build had me fooled by the first video love the instuctable!!!!
Well, this is a really nice looking ornament, it would look neat at anyone's living room (or office), but... certainly: it is *not* a &quot;perpetual motion machine&quot;, because... well: the wheel gets the energy (power) from the water (thus, the wheel's power supply is the falling water), and the water from the pump, and the pump from motor, and motor from DC power supply, and so on.... <br><br>Nevertheless, I repeat it: it is a very nice looking model.<br><br>
You read the material list but not the instructable? No one claims this to be a perpetual motion machine. It is a recreation of a drawing in a novel, it is a work of art, an illusion&nbsp;as the drawing represents an impossible machine, a perpetual motion machine. Thus the use of&nbsp;an electric motor to create the illusion. As a work of art, the creator named it, and it's name? <em>PERPETUAL MOTION MACHINE.</em>
hehe good compositing and use of realflow and 3D prog :P but let's face it , there'll be a lot of &quot;jokers&quot; uploading things instead of real projects ; )
What are you talking about? I understand others making comments about this not being real, but yours surprises me! Did you too fail to grasp this is a real project but one of illusion not &quot;<em>fakery&quot; </em>? If you read the instructable you may indeed change your view of this work of art.
As long as there is power going to the &quot;perpetual motion&quot; system, electricity, it is not considered to be perpetual motion. Perpetual motion is powered -only- from power generated by itself. Another thought I had was that an evaporating substance, like water, cannot be used. A perpetual motion machine will run forever with out any outside assistance.
Unfortunately you misunderstood this project. It is not a perpetual motion machine, nor system, nor an attempt to make one. It is however a glorious illusion taken from a novel and re-created as a working illusion. I see you signed up for Instructables.com just to make this comment? I will not judge, but rather suggest you too remove your comment, actually <em>read</em> the instructable, perhaps marvel at the work of art with a <em>new eye</em>, and check out the other cool stuff here at Instructables.com
FAKE
Daniel, What are you saying is fake? Fake art? You, like those who cry &quot;FAKE&quot; on YouTube, almost always do so because you do not understand what you are looking at. Since you are new here, I would suggest you delete your comment, go back and actually read the instructable, and we'll all just forget the whole thing ever happened. However if you wish to leave the &quot;FAKE&quot; comment, just know that in the instructable the artist explains why this is not a perpetual motion machine. but rather a form of art named <em>Perpetual Motion Machine</em>..&nbsp;
LOL !!! Really ?
What's fake about it? It's a working ILLUSION.
Wow, didja actually read the instructable through, or watch the video and comment? &gt;.&gt;
What gave it away for you sir, the parts list that showed the variable power supply and the electric motor, or the paragraph stating that perpetual motion is impossible? <br> <br>All said, that was a lot of work for a NEAT illusion!
Really? I would have never guessed if you hadn't commented with a caplocked &quot;FAKE&quot; reply...<br><br>
