Heh, funny you do that with squared faces.
At some point I was considering to do an activity like that early this month, but lack of time killed it, heh.
Practically we would be pixelling "pixels" with faces using the board's colors (or similar) and then make different compositions with them.
I really like these, but I have to wonder what's wrong with the old smilies?
Will the option of different smiley themes be available?
There is nothing wrong with the old smileys, just trying to get more smiley sets.
And yeah, I believe they will end up being selectable so you can pick whichever you like (as long as the forum has an option like that).
