Real Penrose Triangle
The Penrose triangle (here dcorated with playing dices) is a very traditional form of optical illusion which seemed very difficult to reproduce in real life and in 3D.
Up to we’ve seen these two impressive realisations:

M.C. Escher for real and in video

We have to admit that we all thought it was only an optical illusion up to this video demonstration.
Or should we follow the counter-explanation showing that this is a simple perspective trick:
Crazy nuts
M.C. Escher in LEGO bricks
M.C.Escher paintings and engravings are playing havoc with perspective and the way our senses and brain build and internal image of what is visible. I would not believe it possible to reproduce them with such a rigid structure as the one provided by Lego bricks.
Andrew Lipson is not the guy to be stopped by mere impossibility. He started with a simple deformation:
After this little play, he went to much more serious work, one engraving that is not possible in the real world. A few inconsistencies, but a good copy of one of the most famous M.C.Escher paintings:
My preference goes to Relativity (and what it reminds me of the movie “The name of the rose“, with Sean Connery):
Then, a completely warped perspective made out of these little LEGO bricks:

Reverse perspective
This video was created to illustrate True Reverse Perspective.
True Reverse Perspective from JMS on Vimeo.
You will notice that the perspective is totally reversed (near objects are small and far ones are small). Slightly perturbating for the senses, indeed.
Impossible perspective
Interestingly, one of the simplest optical illusion has been built in various sizes allowing to see it out of a book or your computers screen. Real life sculptures, I mean. Francis Tabary made most of these.
