Mike:
Before you get the idea we dealt with tweezers and lots of parts, heres how the Zebra was made.
1) Engrave B&W photo of zebras into wood. 12 minutes.
2) Flip and reverse image and burn into a piece if 1mm veneer to 3/4mm deep ( picture shows result).
3) Apply glue and push veneer into wood. Let dry.
4) Sand away 1/4mm of veneer.
