Thanks. I can't really afford a new keyboard right now. Yes, I've seen a few glow-in-the dark keycaps, but I don't think they'd be as good as reflective. By reflective, I mean like the adhesive decals you can get to stick on bicycles etc. That stuff reflects really well and would work just as effective as a backlight I reckon.
Oh well, I'll have to make my own somehow...
