Remote control things have never been of particular interest to me until I saw Angry Dog Studios Gizmo this year at DragonCon. I saw Gremlins at the drive-in as a kid and had several plush and plastic versions, but never this. I had hoped to create a close-enough version for myself but won't get it done today. It's a definite must, though!
His Gizmo is featured below with MKY-MSE-17, also a hand built mouse droid by A Doom for Clankers.
If mogawai's aren't your thing there are plenty of other options. Perhaps a DRD from Farscape?
Or perhaps you want to start planning a Teapot Racer for DragonCon next year?
