Kinetic Sculpture: "Sine Machine"

Picture of Kinetic Sculpture:

I know I don't have time to build my machine in the real world just yet, but I put it together in the CAD world first. The idea is to have a lot of simple moving parts that create an overall, fluid look. I have designed it to be operated by hand but you could just as easily run it with a motor, miniature wind mill (for the greenies) or better yet a hamster wheel.
Practically speaking, you could also use the machine for student demonstration to illustrate the basic sine wave or the difference between wave and particle movement. Mostly it is just meant to look interesting.
Thanks for checking out my first Instructable.

Material: (Use whatever you want, this is just what I would use)
-One sheet of foam board for the base
-1/4 in balsa wood sheet for the Cams
-1/8 in base or ply wood for the Levers and uprights
- 1/4 in dowel
- Straw just big enough to slide over the dowel
- Light weight thread
- 25 heavy glass beads or fishing sinkers
- Glue
Tools:
- Drill x (Drill Press) & Assorted bits
- Small Triangle File
- Hobby Knife and Sand Paper
- Band or Scroll Saw (CNC Router or Laser if you’re lucky)
- In the absence of the CNC machine, lots of patience

This is amazing I am looking into making a kinetic sculpture.

I made one of these for my science class, it only had 6 (maybe 5?) levers and was very rudimentary, but it did the job and got me an A. Nice writeup, the 3d really captures the process well.
akward i am makeing one fore science class 2

Very detailed, well made instructable. I actually just programmed a simulation similar to this; I'm positively fascinated by this simple contraption!

If you have Google Sketchup or are willing to download it for free from google , I just added the full 3-D file to the first step. Feel free to play with it.
Well, done...
What cad program did you use?

It would be fun to make/build!

I used Google Sketchup. It is a great program considering it is free. A quick google search can show you were to down load the program.
