OK, I got a bit carried away this evening. My Dad's ancient PC died and he asked me to give it a decent burial. So I stripped it right down, rescued what bits I could, dismantled his old hard drive and literally folded and repeatedly hammered the hard disk inside to render all data irrecoverable, and then went to the brain (the CPU) which sits under a huge aluminium heat sink. I then let my camera loose and here are the results. Apologies, only one is really in the vein of this "yellow" theme we're having, but I hope you can see it was fun!
