It's an understatement to say that I have a thing for accessories that light up. My keyboard can glow three different colours and has a dimmer switch. Here is a personal indulgence, then: Razer's latest Tron mouse. It glows bright blue, has a 5600dpi 3.5g laser sensor and a glowing detachable energy disk that you can throw at the faces of your enemies. It also masquerades as a light cycle. One of the last two facts is untrue. Guess which. Moving picture proof is below the break.
When used with the Tron mousemat, it leaves Light cycle style trails of light behind it as you play. Yes. This is actually real, and can be in your hands for $100 when ordered from the Razer store . There's a sleek, glowing Tron keyboard coming as well, though it's not yet released.
Here's a video of it doing its thing.
