Years ago I came across, on this site, a math book by a Russian author that's just a carefully arranged sequence of geometry problems. Moreover, each problem is solely a picture with nary a word on the page. As I recall, the reader has to use previous results to solve subsequent problems.
I can no longer find it in my bookmarks and I've searched online in vain. I no longer remember the title or author. Would someone on this site know the book I'm thinking of?
Thanks Sanjay
