You know your car is somewhere in this God for- saken multi-storey car park, but where? If only you had the microphone key-ring (right), you would be far from here. Just push the red button, record an eight second message, and replay it any time. It could be directions, a phone number, an address, or even the location of your vehicle in a multi-storey car park.

The microphone key ring, £7 sterling (€8.89), is avail- able from The Gadget Shop in Britain, telephone 0044 1482 626406.
