If you find yourself at a bit of a loose end this Sunday (6 June), you might fancy strolling down to the NotCon conference in South Kensington in London.

Billed as "some sort of answer to those cutting-edge technological get-togethers they're always having in the USA", NotCon is a one day conference looking at the things technology was never supposed to do.

So, what can you expect for your money? (A paltry £4 on the door, and £3 if you are a blogger, or under 18). Well, quite a lot, it seems. The line up includes speakers such as Brewster Kahle, board member of the Electronic Frontier Foundation and Ian Clarke, architect of Freenet. The event will also be host to the launch of a new project in e-democracy.

But if policy is not your thing, there will be plenty of gadgets and gizmos on display too. There will be demos of social software, MP3 remixing, a debate about whether or not blogs have any real impact on the world and how to tell the time using only a prawn sandwich and an old BBC Micro.

Yes, that last one was true. It seems that given a baseline and some previous sandwich based experience, it is possible to monitor the gradual decay of a Marks&Spencers prawn sandwich and use it to track the progress of time. Clearly this has to be seen to be believed.

So, details for your diary:

WHEN: 11am-7pm, Sunday June 6th, 2004. WHERE: Imperial College Union, Beit Quad, Prince Consort Road, South Kensington SW7 2BB (nearest tubes South Kensington and Gloucester Road). COST: £4 on the door, £3 concessions ®
