Looks like Digg found a copy of the Tetris valentine I've been hosting on my server since February 2006. The original was created by Mitch at the wonderful 4 Color Rebellion gaming blog, but when I tried to redirect the requests to their original entry, the traffic shut down their server in a few minutes.
So if you're looking for the valentine, here it is. Click it to see a full-size, print-quality version on 4 Color Rebellion's site, and see their other 2006 Geek Valentines.
And if you like those, don't miss 4 Color Rebellion's geek valentines for last year and this year! In 2007, they made adorable Phoenix Wright, Nintendo DS, Wii, and Metroid Prime valentines. This year, it's a set of valentines for Dr. Mario, Mario Galaxy, and Wii.
In case you're 14 years old, relatively new to the Internet, and/or coming from Digg, here are a bunch of other two-year-old links you might have missed: Halo Babies, Ze Frank's On Valentine's Day, A Very Star Wars Valentines, All Your Heart Candy Are Belong To Us, a set of vintage 1980s Valentines including Mario, Zelda, and TMNT, vector art of Ralph Wiggum's valentines, more original Nintendo valentines, and nothing woos a lady like romantic Perl poetry. Want something more fresh? New this year are the Team Fortress 2 valentines, Ironic Sans' Scientist Valentines, Jacks of Science's Science Valentines, Diesel Sweeties' E-Cards 2.0, a DIY pulsating LED heart card, interlocking Moebius strip hearts, and Woot's superhero comic anti-valentines.
