Just a quick little thing I threw together to see what random notes would sound like. Click the flag to generate a sequence and press space to play.
Obviously a lot of the combinations don't sound particularly pleasing. The challenge I had in mind here was to keep generating new ones until you find something you like, then try to make a whole musical piece with it! If you're into noteblocking or something like that but have trouble coming up with original tunes, then a randomized theme could potentially be a good starting point.
