>From my Maker Faire experience, noisy things need to be loud to be heard, and 
there will be 3D printers all over the place, yes.

I like the floor turtles plan. I could help restore them. Perhaps we could do 
the optical punch-card thing as a way of programming them. I'm picturing a 
device that holds cards vertically with a motorised thing that moves along 
them reading the punched holes. Could do simple loops for drawing polygons 

I also like the zeppelin, controllable, with camera. Big screen on our stand 
will bring in the punters.

I fully intend to bring Twitbeeb, and possibly another BBC/Raspberry Pi combo.

Depending on whether the National Museum of Computing are coming we should 
definitely get a few or more exhibits from John's Museum of Computing. These 
will need volunteers to mind them, demo, keep the stickier fingers off, etc.

We'll need to get some more marketing materials printed up, t-shirts, orange 
plastic cogs etc.
