On two separate sites I've recently had to implement a rotating image banner that could optionally be linked to paths within the site or to external URLs. Originally I tried a (mostly) self-contained module that matched the feature set called Rotor with some success but really needed greater flexibility. Undaunted, I rebuilt the functionality using a custom content type, a few CCK fields, ImageCache, and Views with the Views Slideshow plugin.

I've always been a big fan of ASCII based games. If I sit down to toy with a project, more often than not I'm doing something ASCII. I was never a great artist, but I loved Roguelikes (ADOM being my favorite) and had a mind to write a multi-player Roguelike back in the day.
