Concept: Jack walks down the cellphone aisle of an eletronics shop. As he passes, all the phones start glitching up (some only screen-wise, others system-wise too. Some randomly try locking/unlocking themselves, distorted voices hiss from the speakers, notepads get filled with glitched letters). People around are staring warily, but Jack notices nothing out of the ordinary. No one dares to approach him.
