As an aside, any resources for learning whiteboard techniques? Not specifically solving algorithms on whiteboards, but designing and conveying information during architecture planning/etc?

I feel like there's two angles to this; 1. understanding complex algorithms commonly used as tests. 2. understanding how to convey information on whiteboards efficiently, common paradigms, etc.

#2 is what I think I'd actually enjoy improving. #1 is just SAT style stuff that I infrequently use in my day job and serves as an annoyance more than anything.
