While it may appear that Instructables contributor dimovi has been staring at a blank, white computer screen for hours, he's actually getting some super secret work done.
Dimovi hacked an old LCD monitor with a knife, paint thinner, superglue, and a pair of 3D glasses pilfered from the movies to create a privacy screen that keeps prying eyes at bay.
I know this all sound very MacGyver-ish, but it's actually pretty simple.
Remove the polarized film from an old LCD monitor that has been stashed in the back of your closet. Clean all the gook off the monitor glass. Reassemble. Replace the lenses of the glasses with the polarized film.
Ta-da! Your monitor will look blank, but you'll be able to see what's on it with your special glasses. Full details for the hack are available on Instructables.
While this hack has some obvious benefits for top secret work done by the likes of James Bond or Jason Bourne, the average geek is probably considering the gaming applications.
Imagine whiling away the hours playingrather than crunching spreadsheets. With a dual-monitor setup, you can keep one legitimate screen open full of work and the other full of hidden fun.
