Sketches and throwies

Doing a few sketches with oil pastels, with a rather nice set of Sennelier artist quality pastels.
I haven't used oil pastels much recently, usually working with a selection of different soft pastels.
My problem with soft pastels is how to fix and store them easily. I am working on organizing my work into different folders and so on, not something that comes easily to me.

Following a brief article on the Graffiti Research Lab, and the idea of throwies,( link is to video about throwies) little LED lights fixed to batteries and thrown onto urban structures vehicles ect. I decided it might be one way of working with lights, and I found a supplier of LED lights and ordered a few to experiment with.

The Graffiti Research lab has a good website with photos and videos of various interventions including clever uses of laser tagging and filling in by computer. I like the idea of using something temporary and harmless to make comments on social and political issues. It's almost incongruous the idea of pretty little coloured lights making a statement about war for instance.
