Yes, I am still working on MARVIN, but for the last few weeks I have been spending some time on a really neat project. It is an Microsoft Excel spreadsheet that converts old RTTTL ringtones into a language that the NXT can read. I have converted about 100 songs so far, and I keep tweeking it to make it work better. Right now it converts to RobotC and NXC. I hope to add more languages soon.
Here is a screenshot of the file.
