I’m putting these here for now as some examples of things that I’ve made.

Jonathan Sanderson has made videos of two of my demonstrations. My ballistic take on the swinging-a-bucket-of-water-upside-down demo won me Best Demo at the British Interactive Group Event in 2005. And these creations work on the same idea as mobiles, even if they don’t look like it.

Alom Shaha filmed me talking about an arch that shouldn’t work.

Here’s a chain reaction machine that Chris Wallace and I made in 2011 for Edinburgh International Science Festival.
