Remember the days before Wiis and the Internet, the days when all you needed to keep kids busy for hours on end was a box full of their favourite branded building blocks?

Well to take you back to your childhood, here we have some of those blocks - but with a little secret inside.

Hiding away underneath their plastic shells is a 2GB memory stick - enough to hold thousands of documents for work or school, or up to 2600 audio files.

The iBlock memory stick costs £24.99 and is available now.
