Iconing. Or ... attempting at it.
My first attempts at making icons using Griff's tips. I still couldn't figure out what you were talking about with the grouping, Griff, but thank you for the other tips. I was in awe when I finished my first icon there (far left).
...Yeah, this is what I was trying to figure out last all night long.
When I'm more sane, I'll probably actually consider correct angles when applying shading. *slinks off in embarrassment*
