Laser living room set
UK design collective UnitedVisualArtists created this careful arrangement of lasers, mirrors, beam splitters, and other optical elements to produce a Tron-y room full of intangible furniture as part of an exhibit called Speed of Light. I hope they set up their next display in a church so I can blog it under the headline “Pew-pew-pews.” [via Geekologie]

Quick ‘n dirty laser light show

Edible Lasers
A friend of mine claimed you can make a laser from a gin & tonic, and so I had to find out more. It turns out that not only can you make a very poor laser using ethyl alcohol, you can also make one from Jello! Well, not the actual Jello like you’d find in […]
