Here's a little side project I did a couple weeks ago.
It's an app for babies that shows a lot of bubbles that you can pop, and they make some musical noise. I made it because we were unable to find one that we liked.
If you have a baby and an android tablet, I'd love to get your feedback! I'm charging a dollar for the app, but if you don't want to pay me let me know and I'll add you to the beta.
I'm totally open to suggestions and feature creep. This was really easy to make and pretty fun, so let me know if you'd like to see something/else.
