You may remember my Musician (open source) Python project for S60 - mini-piano, metronome, tuning notes? Well, it's been heavily tweaked (with help) and there's now support for the hi-res screens of the N80 and E70, in addition to all QVGA varieties. Plus it's faster and less likely to crash. Perhaps more importantly, it's also a better example app to learn from when starting out with Python? Here's Musician 3.1

(Thanks to William F Dudley Jr for the menu restructuring and rewrite of the Piano note code.)
