Sadly Steve despite trying I can't get eccentric, it doesn't suit me. I've heard stories of poeple doing their maths under starwells with whiskey, others ONLY doing work whilst watching the washing machine spin and even of one who covered his whole room in aluminium foil. Sadly for me, plenty of light, a clean work surface and all my books help me best and although I mutter to myself, most people do whilst doing my work!
