This is a concept design for a laser dartboard. The unit can go up pretty much anywhere and is built from a central hub which projects the laser design of the dartboard out in a radius and darts with gel heads.
I’m not sure how sticky the gel darts would be after hitting the floor a few times but I much prefer the concept to flying spikes.
The designers are Seonghyun Kim and Yunjo Yu who are a prolific partnership responsible for many interesting ideas.
