Gigantic liquid crystal display is like a giant calculator

Some say he turns on his soldering iron by saying, “Flame on!.” He deadbug solders – QFP packages. All we know is he’s called [stig] and he sent in an awesome an awesome video of a new display at the Nature Research Center in Raleigh, North Carolina. It’s a 10 foot by 90 foot LCD display that uses 6 inch square glass panels containing the same liquid crystals you’d find in a calculator.
The display/installation is called Patterned by Nature and is built using 3600 pieces of LCD privacy glass. When a voltage is applied to the glass it changes from clear to opaque. While this technology has been around for decades (just look at your calculator), only in the last few years has LCD privacy glass come down in price to make a project like this economical.
The gigantic display was created in part by Sosolimited, an art studio who has made a similar project before. The display hanging in the atrium of the Raleigh Nature Research Center is amazingly efficient for its size  drawing only 75 watts.
If you’d like to try your hand at a similar build, we wish you luck; this LCD glass is still somewhat expensive but perhaps in a few years the price will come down enough that we can play Tetris on the side of a building.
