Say hello to the latest weird watch: the Kerala Trance. Sounds a bit Ibiza to us, but it's got a geek angle too: the display's in binary. Two rows of four LEDs tell the time; hours above, minutes below. Next to each LED there's a number - add up the numbers whose lights are illuminated and you get the time. If the LEDs marked 8 and 1 are lit, it's Nine O'clock; if the lower-row 16, 8, 4 and 2 LEDs are on too, it's 9:30.

Maybe that's not the kind of mental gymnastics you want be doing if you're trying to catch the last train home after a evening in the pub, but you get the idea. It's easier to decide whether you want to shell out the £100 UK distributor Firebox wants for it. ®
