He just put some acetone (or anything else that is volatile and flammable) on the mouse pad... It soaked into the neoprene and the vapors are burning... This works really well on concrete as it is very porous so you can get a decent amount of acetone in there... Freaks some people out to see the concrete burning
Oh, and do you have a higher resolution version of the second of the pic of whatever it was flying around? I think my desktop might be a bit brighter than before

I would guess a short-lived butane puddle or acetone initially.... but it's kinda in mid-air and there's nothing shiny on the desk =P

Yep, butane was used. And it needs much more of a procedure than being just 'poured' in there.
Acetone, gasoline, etc. would probably blow me up , don't even think of doing such a thing.
Mouse pad and wood are much more flammable than concrete!
I filled a abot 3cm iwde, 15cm long cardboard tube with butane to the top and ignited it. It burns slowly in top of the tube.
Then I trigger the camera (in dark room) and quickly lift the tube up. Air rushes in it from te top and pushes all the butane to the bottom, and it blows up pretty violently. It happens so fast that almost no heat is transferred to the surface, even if it gets quite licked by flame.
First few pictures I took were actually 'preparations' for this :P I especially like the look of flame in first 'brning hand' pic but I had to move my arm :( Also bigger pic here for Peter K. (Sorry this one was taken as 640*480, but I didn't seem to get much quality degradation by sizing up.)

Absolutely great, how did you get such a tight crop on a lightning bolt? Luck? Personally I've only had bad luck with lightning photos, it just never strikes where you expect :(. Double exposure or photoshop tesla coil + landscape is probably easier
Sun{rises,sets} are a bit more predictable, here is a morning shot of typical Finnish archipelago from last weekend:
