Lavalamps in action Originally uploaded by mahnve.

We’ve finally got our act together and got ourselves a pair of lavalamps. They are controlled by CruiseControl and green equals all tests passed.

When reading about other people doing this, they say that these things need to be turned off every ten hours or so. The only warning notice on ours, bought at Clas Ohlson, says to not drink the fluid - duh.
