Not so sure that this is quite as cool, but if you’re in the right country it could be very useful. Ladies and Gennlemen, I present to you the world’s first Anti Mosquito software package. Written by a Thai programmer with obviously too much time on his hands. Apparently it works by broadcasting an audible sound at a mosquito unfriendly frequency around your PC. Clears the little pests for up to a 2 metres radius from the PC. Won’t run on XP though. Hah!
