This version of 2D building is done by Nima Motamedi. Inside this post you can see some more amazing photos taken, and kindly submitted by Nima. This particular building looks like it lacks 3rd dimension. Do you agree? I can’t understand how people manage to live in these :) Still, it would be cool to visit “worlds thinnest apartment”, right? There are two more illusions that match this one – check out transparent 2D building and flat flats.
Nima also added detailed description: “Hey I go to your illusions site when I’m bored at work and I love a lot of them (especially the 3d chalk drawings). Anyway I wanted to help out. I live in San Francisco and was walking around Union Square with my camera when my girlfriend spotted this building. We looked at it and it looks like there is no side walls! The attached pictures show it from the illusionary angle and a different angle and you can see that its really a triangular building”.
