It looks like a ship piece. Judging from the technicolor jumble next to it, those might be the specifics as to the collision and details of how it has to come out. I remember seeing a similar process for custom sprite ships in Starbound; I am most likely horribly wrong, though.
i'd like to say that I did not create the piece on the left only the awesome technicolor piece on the right close, though
Alright alright alright alright alright alright alright alright alright alright alright alright alright alright alright alright... Beyond that, I got nothing.
