I've watched lot of your videos .. you provide great architectural content! keep it up!

When the title said "impossible building" I immediately thought of Zaha Hadid then when E/C/ Escher came up I realized what you meant. I did not realize how few built buildings Hadid actually designed, being mostly in academia. I already have many more built projects under my belt than her, much to my shock. If you look at work that is built and fully hers, the list starts in 1993, when she was already 43! I never realized that.

love all your videos...,

It's really good.....

cool

Which app did use?
