THIS. IS. THE WEEK ! Street Fighter turns a quarter of a century old this Thursday, so we thought we’d kick off Unity’s weeklong celebration with a couple of items you can enjoy throughout this great interweb of ours [ UPDATED 8/28 with more fan requests! ]

Right Click and Save As, friends!

Assuming you’re as excited as we are to ring in 25 years of Fightin’ in the Streets, we’ve cobbled together a couple of animated avatar icons you can use to show some World Warrior love. They’re fully optimized specifically for teh Twitterz ( see how mine looks! ) but we imagine they can live on elsewhere too. Your IM icon, Myspace page, your eHarmony profile, etc. You know, the important places.

Feel free to drop a request in the comments below, and we’ll whip one up for you if we’ve got the time. All we ask is that if you feel like showing Street Fighter a little love on its 25th B-Day in Tweet form, drop in the hashtag #SF25 . Nothing would make us happier than see a Twitter feed choked with a sea of looping Street Fighter animations.

UPDATED! With requests from Russel and Rammstein:

As requested by Maxemillian and E.B., here’s Bison and Sakura!

By popular demand, Honda headbutt and a very sad Dan!

Because you demanded it, Cammy’s win pose and some specifically requested SFIII representation!

Ken and Ryu get friendly, and finally some Akuma love!
