Something about this retro brick pattern for Illustrator reminds me of the Brady Bunch. I remember some texture in their house seeming something like this–of course, it’s probably just my faulty memory trying to make the connection…

A word of warning: the download is a swatch file (it looks like an .ai file, but appearances can be deceiving). You can drag the file into your swatch folder upon downloading so you can always have it, or just open it and open your swatches palette to use the pattern. FYI—it will look like a blank file because it’s just saving the swatch pattern info, so look in the swatches palette before getting really frustrated!
