Module vr Customer can try spectacles on face b4 buying

Hi

I am looking for module in which a customer can see on its face how does the product looks before buying.

like spectacles or hairs

What i mean - Option for customer to upload his face photo via camera and then he can view the product how it looks.

I have not seen something like this around OC, to my (limited) knowledge. Possibly, because it would be above the usual price-range anyway, due to the relatively 'small' market potential, compared to the programming time investment, I assume.
Check under T-Shirt Stuff, on the extension Pages, they are doing similar things, to create/order CUSTOM BRANDED Shirts, so, you may get at least an idea, on how something like this eventually 'could' function.
