Glasses which subject their wearer to a strange sound and light show have received a generally positive review.
Jeff Bordeaux tested the Trip Glasses for Gadget Review and gave them four stars out of five.
Describing the experience as a "personal light show", Mr Bordeaux said the glasses are likely to appeal to people who like "Magic Eye" style art.
He added that he enjoyed the 14 minute show but noted that the glasses should not be worn for too long and had not been as keen on the accompanying sounds, though wearers can leave out the earphones.
They may also be a good idea for Halloween, as Mr Bordeaux noted that they give a distinctly eerie appearance when someone wears them in the dark.
