Code Highlighting Plugin

Hello folks,

Awhile back I read about a WordPress plugin that applied special color and highlighting to code placed within a block. Somehow it was able to identify the programming language and apply color schemes to make the code easier to read (kind of like what Notepad++ does).

Foolishly I didn't bookmark it and haven't had any luck tracking it down. I think it was like Glight or gHighlight or something similar - as I said I've searched around quite a bit with no luck.

Can anyone suggest a plugin that does this?
