Sorry, it won't enable you to time travel
If you happened to be standing on your toilet hanging a clock, slipped and hit your head on the edge of the sink, you may have had a vision.
Now you can make that vision come true! DiamondSelectToys.com have a replica of the Back to the Future Flux Capacitor, the thing that makes time travel possible, available for pre-order at a cost of $275. Though the expected availability is stated as 04/30/2008, it's more than enough to get geeks like myself excited.
The Flux Capacitor features full light effects and measures just over 16" tall and 12" wide. It won't however require 1.21 jigowatts to get it started. This has to be the ultimate gadget for any car.
