A wireless orb has been developed which tells you how your investments are doing.

The orb, prototyped by Ambient Device, of Massachusetts, is expected to cost about £20. It glows green to tell you if your portfolio is up and red if it is down.

The first version has been designed to work on existing pager network but there are plans for versions based on Bluetooth and Wi-Fi wireless technologies.
