These bottlecap lamps come in a kit with some of the caps included; the owner can customize the pattern and colours by using different caps from 2L plastic bottles. I likey.
Thanks to a reader named L for the tip.
Here’s another neat idea I posted about a while back- clever people in Brazil lighting their homes using “skylight bulbs” made from plastic bottles filled with water.

This video depicts a bunch of people in Brazil who light their homes with plastic bottles of water wedged through holes in the roof. The water acts as a reflector, bouncing the daylight all over the room. In the video you can see them popping black plastic film cannisters over the lids of the bottles- they do that because that type of bottle comes with a cheap lid that cracks when exposed to sunlight for too long.
Each bottle gives off about as much light as a 50w bulb, reduces energy use, and is a clever way to divert those bottles from becoming waste. This whole idea made me really happy.
