This are scans using Ladybug, the motorized microscope and 3d scanner for small things made out of Blu-Ray players!  

Scanning a phone screen is interesting (Ladybug art, above). Click on it to get the full resolution. This is at the lower res mode --- not as extreme, kind of artistic even! We needed to get an app to prevent screen timeouts, and then just... stuck it on there with a bit of tape. If we got it a bit more level, it would reduce some of the variation throughout the image. Or, alternatively, you could implement autofocus. 

The original is on instructables --- if you notice a hint of green, that's actually a consequence of the stitching process --- the raws are perfect! And so the nonprogrammer cried into the night, for someone who would kindly rescue him...

And then my good pal Yujie boy came back to the lab for a day, so we scanned his face, too. Held still for 106 minutes. Darndest thing I've ever seen.
