It 'lures' your children outside and 'tricks' them into moving around!

First the Nintendo Wii, now THIS! Next scientists will tell us that exercise is good for children! I say, PSP and a packet of crisps.... Just kidding!

From engadget.

We saw a few clever products at Toy Fair 2008 designed to get kids up and active, but none so nefarious -- and cute -- as Swinxs. The "toy" is basically a talking computer with an RFID reader, that guides kids through different pre-loaded games or stories. The kids wear RFID wrist bracelets that identify them in the game, and let them interact with the machine. We heard, from a reliable source, that if kids engage in this type of "running around" in "grassy areas" they very well may die, but that's all hearsay. Once kids grow tired of the included games they can download and install more over USB, and there's a free SDK for developers to create new entertainment for Swinxs. No word on a price or release date, but hopefully we'll be seeing more of this one as time progresses.
