What I envisage:
An array of 32x32 or 64x64 leds which obviously would need to be individually addressable.
RGB awesome but monochrome LED array acceptable.
'Display' size of about 300x300mm
A low resolution camera (obviously doesn't need to be greater than 64x64).
'Live' transmit the feed from the camera onto the array so that a face is recognisable as a face (but of course given the lo-res not a 'particular' face).
Steampunk project, also why not ?!
So firstly is this possible and if so, any guidance as to how to go about it and what parts would be suitable/ideal would be VERY welcome.
