I was going through some old bookmarks and I came across this. It's a collection of online interpreters for an impressive set of programming languages. The website says that there are "260 practical and 420 recreational programming languages, for a total of 681 languages."<p>There are some odd omissions: ALGOL-68 is included, but ALGOL is missing. Pascal and Oberon are there, but none of the Modulas.<p>Some of the more "interesting" (to me, at least) programming language names include "Bitwise Fuckery, Hodor, Lean Mean Bean Machine, Pyramid Scheme, and Bitwise Cyclic Tag But Way Worse".
