how about sad faces when you have like 50% and neutral ones when you have 75% and smiley for 100% ???

smilies are rapidly disappearing ;P

apparently our science is happy

or maybe smaller with no face and no thumb, and then you gain a face and then you gain a thumb ?

Without thumb programming and java applet smileys look the same

only a matter of changing the color to pink or so

you guys are addicted too the smilies.

No, I "treasure" it (only 1 left )!

Nice idea

Here they are. But I think it's kinda confusing at the beginning.
