Awesome Hud

This low-cost gadget adds a heads-up display to any car. It uses your phone’s screen as its projection source, which reflects onto a see-through screen you can attach to your dashboard. It works with a variety of smartphone GPS apps to display your speed and driving directions, so you can keep your eyes on the road ahead.

Iris uses a 720p laser projector and a transparent screen, and sits just above your head so it won’t block your view of the road. It shows directions and notifications and lets you answer calls and text with gestures and voice commands.
