The LaserCube is a mountable projector that displays GPS directions on the road in front of you. Using a laser, it can also create text, images and animations.
The LaserCube could be a gamechanger for anyone that frequently rides at night or needs directions to various destinations, like gig workers for UberEats, DoorDash or TaskRabbit.
Some LaserCube owners are doing really cool stuff, like 3D mapping, light shows, and more (check out some owners' projects on the LaserCube website).
This somewhat bulky device has a bulky $1,000 price tag, but customizable as it connects with various smartphone apps.

Here's a 25-second demo video of how it works.

I'm not convinced this is worth it's weight just yet and am looking forward to even smaller versions of this, possibly with multi-directional lasers so the rider can also display virtual lane markers (like this Amazon bike accessory) alongside where they're riding. Then it'd be multifunctional for safety and GPS!
However, if I went on more group rides, I could see this being a really fun way to share the route directions with everyone else and use animations/images to give shoutouts to fellow riders or celebrate birthdays and other occasions.
What do you think? Do you need one in your life or is this entirely unnecessary?
