Well, I think it would be most impressive if you could mathematically prove
it using quantum entanglement. You may even get the Unix admin's job:) I
have to put my money on Stephen Hooper, except, how long does it take to get
into this lightproof, waterproof, airtight box? Long enough for the bulbs to
cool down? Is this software engineering firm Google, by chance? I heard they
do things like that.
        Also, note the use of wood. Why not steel (or some metal), like most
electronics are housed? Assuming the bulbs are not LEDs and that they are
substantial enough to create heat (and those little Christmas light bulbs),
they could possibly heat up the wood.
