Another emoticon for klubitus.org. This is actually one of my own favorite designs - ever. You see, they wanted a stop sign, yet the pixel limit was quite strict so I thought it could not be done. After zooming in and out on some initial sketches I noticed that with such a small sign you really don't separate the spaces between the letter, and the Stop-sign being such a familiar sign you immediately recognize the word from the overall shape. So I just eliminated the space between the O and the P - and voilá! 16x16 STOP-sign!
