Two concave mirrors project an optical illusion of a TARDIS
(or Adipose)
The toy is well constructed, in black plastic, with an embossed DW symbol. There are no moving parts and no batteries are required, just a strong overhead light source. So as long as no-one stands on it, or there isn't an alien attack; it should last for years.
I found the interchangeable TARDIS and Adipose, which are fixed through the base can be pushed out using a ball point pen, which avoids any risk of damaging the mirrors.
This toy should prove popular with Dr Who fans and lovers of illusion.
