Now Obama has closed down Guantanamo and is publishing dossiers detailing the Bush administration's use of torture, he is perhaps in need of new and effective measures to pressurize nasty people. I humbly suggest a simple and cheap device guaranteed to drive any adult into insanity within a short amount of time: Hama beads.
Anyone with a small daughter will know about these things. They are small, hollow plastic cylinders in a variety of colours. You place them on pegboards to form a design and then iron them (not forgetting to cover them first with special ironing paper (unlike my friend Andrew!)). This causes the beads to melt sufficiently to bond to their neighbours and, hey presto, you've made a picture. Take a look:
Hana and I made this beauty just before leaving for the deserts of Arizona. It drove me mad! The beads are tiny - perfect for six year-old fingers but a friggin' nightmare for an adult. Plus there are 29*29=841 pieces in there! No child can do this many, so I was left with hundreds to do whilst Hana lay in bed sleeping. Plus, there's never quite enough space on the peg board, so when you get to the end, inserting one in the middle pops out 20 around the edges, and vice versa...arghh...Which sadist devised this stuff?!!
