I wouldn't be surprised if there's not even one person out there who knows what I'm talking about, but...

There used to be a device available for the Amiga that was called a "joyboard". This was designed like an oversized joystick (i. e., a ball-and-socket design), strong enough to withstand the weight of an average adult, which had a platform on top instead of a stick. It's original purpose was to accompany a skiing game, in which (similar to some arcade games) you would stand on the platform and your onscreen character would lean/move the way you did.

If anyone knows where I could find one of these, I would be very grateful. If not, but if you've ever seen or owned one, speak up anyway so I know I'm not the only one.
