Enjoying how awesome the laser pointer I bought for my girlfriend actually is - it's purple, but turns blue when pointed at pure white objects...and unlike normal laser pointers, it instantly charges glow-in-the-dark objects when pointed at them - I'm wearing a t-shirt with an effect just like it, and when the laser passes over me, it leaves a glowing line, even in the light (though I'm sitting in the dark) like I've been slashed. It's amazing. Totally worth the purchase...the other one I got for myself is standard, green beam that can hit objects over a mile away, and the beam is highly visible in the dark, not just a dot on the opposite wall. Seems more "surgical" but it's also a lot less fun, and doesn't generate as much light.
So uh, yay.
