I did a little icon design for a client. I thought it came out well.
Here’s round one. It’s supposed to indicate something. Can you tell what it is?

After that they asked for another round with a little direction (they picked other icons they liked and told me about them):

They liked “F”, so I did up a whole series of icons for other things for them.

I think they came out well for “simple” icons. Funny how hard simple can be, though
