The term "gallerycrashing" is a clumsy neologism I have coined to refer to the act of placing an unsolicited artwork in a private or public exhibition. Specialised circuits were constructed for the sole purpose of gallerycrashing and a family of objects called 'Spacehoggers' were gradually developed for proliferation around galleries.
The Spacehogger takes the form of a triangular wooden slab bearing a simple alarm based device and an FM transmitter with a small built-in microphone, literally designed to hog space and relay the evidence to an radio receiver with audio recorder. When it is fully armed, any attempts at relocation activate a failsafe: a 120dB alarm tone, dissuading people from tampering with it or moving it.
