Esoteric Computer Languages Anyone Who Hasnt Seen This

Esoteric computer languages. Anyone who hasn't seen this already should check it out. This site is sort of a clearing house for bizarre programming languages, designed either to annoy the user or to explore odd programming paradigms (often both). My personal favorites are Unlambda (functional programming in hell) and Befunge (two-dimensional control constructs, anyone?). Another highly amusing language is called hq9+, which is, oddly, not linked from the above site. If you like this sort of thing you should also check out this site. I guess this is a classic case of people with way too much time on their hands via [Lambda the Ultimate] by way of [Sam Gentile's Weblog]
