Today’s logo at slashdot.org was created by Jason Jacques, a new PhD student in the SACHI group!
From slashdot.org: Artist Jason Jacques says: “While the main text itself is “obvious” in its fully animated form this logo provides additional challenge in that the remainder of the message must be decoded. Can you figure it out? If so, mail answer to logo15@slashdot.org. How did he do it? After calculating the necessary sizes and bit patterns on paper, the static image of the entire message was generated using Pixlemator on Mac OS X (Lion). This image was then processed using ImageMagick (and a short shell script) using Ubuntu. Additional editing was done to the logo portion in Pixelmator (OS X). These frames were then assembled into an animated gif using Jasc Animation Shop on Windows XP. Finally, the images were optimized to minimise their size using ImageOptim, back on OS X.”
