In the interest of speed, more consistent appearance,and just plain showing off, if you have a peek at my CSS for this site, you'll notice that all of the background textures are now generated with Base64 code rather than tiled images.
This cool thing is possible thanks to Patternify by Sacha Greif and is based on the dithering patterns provided by Strike. Thanks also to candle for giving me the heads up on this tool.
I still crunch images down to 1-bit with Ditherlicious. My original post on this blog theme (Stricken) is here.
