Egads! LED Goggles you can see through (surprisingly well, too)! They pulse subtly, making them so cold and dehumanizing. They were totally perfect for the character I was going after – Mr Freeze. It was my first time really playing with LEDs and Arduinos, so it was a good learning curve hugely aided by the wonderful Instructables community. The biggest lesson here for me (as with virtually every project) was iterate, iterate, iterate! I’ve skipped all that for this instructable though and I’ll show you the steps to the end product!
