Liquid light - painting with emulsion

ANOTHER THING I want to have a go at - developing images on things that are not paper. Liquid light is a paint-on emulsion that you can then expose to your negative, develop and fix like you would photo paper.

How-to is here and here on Instructables (a little more in-depth). There's also a course you can take at Fotosynthesis, a great community with darkrooms near me in Kennington. It's on my way home from work, it'd be rude not to pop in...

I'd like to develop on something not very flat, like the inside of a shell, or the round outside of a skull...
