I just came across these lovely visual mathematical proofs.
For instance consider the following sequence:
1/2 + 1/4 + 1/8 + 1/16 + … = 1
and then see the following image on the blog!!
How cool is that!!!!
I had posted about something similar earlier (see visualizing mathematics).
Note: Before someone gets technical on me, I should admit that these are not “proofs” in the rigorous mathematical sense of the term, but they do provide visual evidence / explanation that helps us understand the underlying patterns.
I also recommend the blog (http://www.billthelizard.com/) on which these “proofs” appeared for a bunch of other interesting stuff about mathematics and programming.
