Hailing all Teachers!
Are you on the right frequency for our brainiest quiz yet? Get your thinking gear round these cranial conundrums and you could win your school a Psion Digital Wavefinder.
This elegantly weird looking antenna, once attached to your PC, will turn it into a crystal clear, interference-free digital radio receiver. You will also be able to play interactive games, record to MP3 and MP2 at the touch of a button and get web audio and pictures without the need for internet connection.
Ladies and Gentleman, the future has arrived!
