Favourite Chinese characters

What are yours?

For me it's 楓. It looks so damn awesome in a Ming font, like it's about to smash somebody. 亞 is cool because no matter how many times I try to memorize its stroke order I forget it every time. 曲 and 田 also look great due to their proper geometric shapes.
Simplified characters I like include 当, 网, 丽 and 杰. There aren't many good simplified characters, but these definitely are.

My favourites are 乒乓。 I love how visually the dot on the bottom moves from left to right to represent the ping pong ball going back and forth.  Some characters are absolutely genius like that.  Other ones are 凹 and 凸, which are concave and convex respectively. 

Otherwise, I tend to like everything with long sweeping strokes like 之.  I can never get them to look quite right with a brush though...
