My visual metaphor thing accidentally switched on the other day, whilst fooling about with a cellphone.
Suddenly, a clamshell phone started resembling the head of a creature (with one half of the shell acting as the articulated mandible of some T Rex-like robot space creature….I really must stay off the espresso).

Anyway, I began thinking about today’s invention: A clamshell phone designed in the shape of the head of eg a parrot, crocodile or whatever. Instead of a ringtone, the creature’s squawk or roar could be issued at the same time as opening and closing the clamshell by a small amount (many such phones already have motors on board to drive the internal buzzer). It might even be possible to lipsynch clamshell movements with the words spoken by a caller.
Design in a pair of flashing LED ‘eyes’ on the top surface and you have a lot of added product personaility in a market saturated with sameness.
