I still carry vivid memories of the mid-1970s, and times seeing MPC's Strange Change model kits on shelves in the Toys R Us at Paramus N.J.
There were three kits in all: "The Strange Changing Vampire," "The Strange Changing Mummy" and the one I wanted more than anything, "The Strange Changing Time Machine."
Basically, each model kit had a kind of switch or flip function, so that two views of the model could be seen.
The vampire could change forms (from vampire to skeleton) and so could the mummy (from whole to ripped bandages).
But the time machine was greatest. It had had one view of an inventor operating the gadgetry or instrumentation of the time machine. And the other view showed him getting attacked by dinosaurs, post-time travel.
I guess these Fundimensions kit might be construed as a little gimmicky, but they are great desk-toppers, and vintage curiosities to look at and enjoy.
I never owned any of these, but I know the kits were all released by Round 2 in 2011. My Dad is a great modeler, so I might ask him to build me (or Joel) a strange changing time machine one of these days...
