Recently saw an article about pancakes in a rice cooker. I've seen omelettes / eggs as well, and perhaps bread if I recall correctly.
You may want to search on soranews24.com, as they have a lot of light hearted articles about things like this.
Here's a prime example:

At the tail end of the article, you'll notice their tags, such as "rice cooker" and "rice cooker pancakes". Clicking on any of those tags will bring up all articles tagged as such and may be a good starting point for your new hobby. Happy percolating!
