Smilies
I almost forgot that I've designed and drawn QQ smilies with Photoshop many years ago. They are 50*50 pixels.
At that time, I found some words we typed in QQ (Tencent QQ, a kind of IM) can automatically be changed into smilies, and the smilies can express more exactly what I want to say than words. So I drew some little smilies for myself. I even used them to write a blog post. However, they are too big so that the layout couldn't be nice. Then I forgot them gradually.
Lately, I decided to organize the stuffs I've done before, and I think they're really a good memory for me and further work. After all, they were the solution for my need.

It's so hard to drew something with a mouse.
