Tech deals: April Fool's day everyday with the Annoy-a-tron 2.0

As it's April Fool's day we thought we'd bring you a gadget which will enable you to keep the pranks coming all year round, and is sure to win you the title of "office joker" if not "most popular employee".

With the onus on the innovation itself, as opposed to it being the best price, ThinkGeek is selling its Annoy-a-tron 2.0 for $13, which can be shipped to the UK.

An updated version of the original Annoy-a-tron, the 2.0 version brings with it a whole new level of annoyance with six sound choices and volume control, whilst retaining its magnet for a wider choice of hiding places.

There's a useful guide to deployment and ideal volume on the ThinkGeek site, so be sure to have a read, and if you have any suggestions of how the Annoy-a-tron is best used then be sure to let us know in the comments.
