It was an item in a charity shop and the staff didn't know what it was..
About 12" square and an 1.5" thick, opening out clam shell style to double that size, white plastic with some black parts. Each side had a
3.5" very slim cooling fan in it and opened up, each side had two lift up hinged arms which could be raised from it. It appeared to be made from a child's type toy plastic.I could not see any obvious way for power to be applied, nor any means to add a battery, I saw what appeared to be some sort of micro switches or sensors, of a type I have never seen before. Staff didn't know what it was, or its purpose.
