What use could I give to an old, but working, iMac G4 (lamp-like model)

Hi everyone,

A couple of weeks ago, I bought this working iMac (G4 - 800 MHz , lamp-like model). I cleaned it and added some more RAM, but I'm looking for cool ways to put it to use. Internet is working, web browser is working, as well as all native apps from back then (it's running OS X 10.3.9 - Panther). I'll appreciate any comment with ideas of creative uses for this vintage beauty.

Thanks.
