Basically Homeless decided he wanted to make an invisible PC. What? He tried using a variety of different off-the-shelf technology so that he has just a empty desk with a piece of nano-particle film that has the desktop projected on by a digital projector.

Parts list:

• Invisible gaming mouse that uses a depth sensing Intel RealSense 435i to translate my hand and finger movements into cursor actions in windows.
• The keyboard is flush mounted with the desk surface and has a plastic mold that perfectly fills the space between the keys, and then is painted.
• The monitor uses a nano particle film suspended from the ceiling with a projector pointed at it to appear as though it’s a floating hologram.
• The whole assembly is wireless, see 10:22

There’s a lot of small details, so it’s worth the watch.
