Poop bots

Places like San Francisco have large problems with human and animal waste in the streets.

Use street sweeper and vacuum technology on garbage bin sized bots that roll through the streets at night and pull all this stuff in and take it to a collection point to be processed.

Could help clean up cities big and small around the world. And could lead to novel new industries that capitalize on the waste material collected.

AR house marker

Beacon that puts an AR logo over or around your house.

Could be useful to support your team, put a cross up, mark where the party is, or make it clear people are not wanted.

AR aquarium

Idea

Aquarium out where as you rotate the phone or lay it flat it changes the perspective that you're looking into the aquarium from.

That way if you lay it down flat you can be looking down into the aquarium from the top, and if you have it on the side sending up on a standard holding it up you can look at the aquarium from the side. You can tap into the augmented reality of it by placing the aquarium on the table and you can walk around it and look at all your fish in the aquarium.

Then you can buy different things to add to your aquarium and finish that you can then all that.
