Google Wave

Google Wave, which combines e-mail, instant messaging and wiki-style editing will go on public trial today.

The search giant hopes the tool, described as "how e-mail would look if it were invented today", will transform how people communicate online.

It will be open to 100,000 invitees from 1600BST, each of whom can nominate five further people to "join the Wave".

The tool is also open source, meaning third party developers can use the code to build new applications.

The developer behind Wave described it as "a communication and collaboration tool".
