Today’s invention is a novelty in the form of a personalised cup.
The base of the cup is made so that when the liquid has been drained to a certain degree (perhaps by using a moulded-in straw), the remaining pools in the base look like someone’s face.
Clever moulding of the base, before attaching it to a standard cylindrical wall element, could even result in the appearance of a sequence of different faces, or changes in expression of the original one, as it is drained.
This would in effect provide the cup with a kind of internal film show mechanism.
This came along some time after my posting:
