Reshade is an image enlarging program for PCs - you select part of an image (or the whole of a small image) and select the magnification, it's then resampled and detail is interpolated to make it look more real. It appears to work, though I think that tweaking it for the best results for any given image will be an acquired skill. If anything it shows how stupid the CSI-style infallible image enhancement and all the recent "martian statue" things are - you add that much detail to an image, it could end up looking like anything depending on how the software is set.
Think it's available for another 20 hours, if you need something like this I think it's worth a try.
Later - here's what I got using this program to enlarge my icon then posterizing the result
