Lego Appeal!

On Tuesday, my using-lego-as-a-model-for-social-networking is being presented at the Durham Blackboard Users conference (durbbu10). Problem is, I only have enough lego to do the experiment with about 10 people, and from what I hear, I'm likely to have more like 30 or 40 people in my session. Help!

What I need is more traditional-style lego for making basic cars, like this:


(you cant really see it, but those black ones are the wheel connector blocks)

If anyone reading this in the Shoreham/Sussex area has some lego like this they could lend me for the next week or so, I'd be extremely grateful! Please email me or comment and get in touch!
Thanks
