Homebrew Applications

Where can I find a list of Homebrew Applications for the Gamecube?

My friend and I were talking(arguing) about me wanting to get a XenoGC modchip, and he keeps telling me that I'll miss out on all the homebrew apps.

We have softmodded Xboxes, so we really enjoy a life of great Homebrew Apps(like Xbox Media Center). We both got an Gamecube recently and wanted to know what can we do with them.
