Román Cortés has produced two CSS ASCII images of Homer Simpson and a certain George W. Bush Jr. The snag, well for the George Bush image there’s 31.82kB of source code, but the Homer one is a bit more compact at 16kB.
Roman first created these images by hand, but he’s now written a Windows program which converts JPEG images to CSS “images”.
Allegedly, there’s an animated Homer CSS page as well, but that server’s been Slashdotted for now…
