15 y.o. X used metalfusion's method (http://bit.ly/p9zAfx) of drilling out halftones on a CNC to create a present for his grandfather's 90th birthday, a wooden "print" of a shot of the two of them when X was a toddler.
For those interested, here are the specs:
- Shopbot CNC
- 90 degree, 3/4 inch router bit
- Image is 23" x 15.7". It has about 5100 dots in it and took about 1.5 hours to drill
