The Lightpack wants you to see and experience whatever is on your screen without damaging your peepers.

What’s awesome is that it’s plug-and-play, which means only about 15 minutes to set it up, and you can tweak it as you see fit (alerts for messages, timers, etc). It’ll cost you $80 for one, which includes the Prismatik software. If you feel as though this would be a better DIY project, they put everything online so you can make one and use it as you see fit.
