If your Friday is beginning to feel like a long trudge up a slippy hill with rocks raining down on your head thrown by bureaucratic monkeys from towers, then our our sister site iGizmo could have just the half-time oranges to make the slog a little easier. They’ve got a horribly addictive quiz designed to test the mettle of even the most hardened tech geek.

The aim is simple: identify ten zoomed-in pics of technological bobbins in as short a time as possible. The winner will go on a leader board and be crowned Lord High Geek and brought tithes, tokens and offerings by his subjects. I made the last part up, but the quiz really is marvellous so I recommend you take a look-see.

Just so you’ve got something to aim for, I did it in 13.6 secs, which is to the top ten what Paula Radcliffe is to the Olympic medal positions.

If you’re still rooting around for fun Friday things to do, can I also point you towards our devastatingly good roundup of the top ten greatest Flash games, and Robokill – which is so good I might name my first child after it.

Enjoy your weekend.
