Years ago my friend Paul V discovered that LP Lik Be re-used their toy puppy eyes as space domes. You can read about this fascinating discovery on his fab SpaceX website.

Those domes are a mindworm. I just cant help coming across rolling dog dome eyes. I've spoken about blow moulds before and here's another one in the US, a large ball visible underneath that propels the pooch along.
This is a big puppy at 12 inches long, much bigger than the LP Space Dog but the same principle.
Paul V has just found one of these doggies pictured in a French Sitap toy catalogue too!
Can you spot any dome eyes readers? Keep your eyes peeled.
Let me know.
