I unpublished this the other day but have been asked by another user to put it back up...enjoy


The Penrose triangle, also known as the tribar is an impossible object. It was first created by the Swedish artist Oscar Reutersvärd in 1934. The mathematician Roger Penrose independently invented and popularised it in the 1950s, describing it as "impossibility in its purest form". It features prominently in the works of artist M. C. Escher, whose earlier depictions of impossible objects partly inspired it.

Step 1: Items Used

1. Balsa wood
2. Super Glue
3. A little bit of magic

Build Time

5 minutes

Step 2: Method

This illusion is all smoke and mirrors. It is obviously a trick of camera angles.

You can make this a big or as small as you want but, I have found that a small one is easy and effective. Cut 3 pieces of balsa wood about 5 cm long, each end should be right-angled. Name each piece: A, B and C. Take piece A and B, glueing at the end so that they form a right angle. Take part C and cut a 45 degree angle at the end so that the longest side is the same length.

See below for plan

Step 3: The Illusion Shown

The best way to see this working is to look at this video:

    Not quite sure how to take your comment? I created it, because I could and just leaving it on the end of my desk creates interest. The original idea came from Escher the artist and was make similarly famous by Penrose, it causes an ambiguity and it is not always obvious. So it has a purpose we just have to say if it is useful or not :-)
