Currently installed at Under Design, the Lava Lamp Clock tells the (approximate) time to within 15 minutes. Each 32oz. Lava Lamp goes on once per day, for a total of 3.5 hours at a time. There are 24 Lava Lamps, starting with 1am on the far left, ending with Midnight at the far right. It measures approximatly 18' wide, and 2' high, and 1' deep. The silver bases reflect daylight hours. The orange checks mark 6am, Noon, 6pm and Midnight. You can click on this image to zoom in.
What Time Is It?
The time it's displaying currently is a bit after 6:35pm. The 3 o'clock lamp is off (goes off at 6:30), and the 6 o'clock lamp has been on for less than an hour, but more than 15 minutes (you'll note the initial lava explosion has happened (15 min. in), but it hasn't melted yet at the 45 minute mark). Once you get used to the regular 'warming up' period of lava lamps, you can predict the time with better accuracy.
