Flipper fan to flipped out?
Certainly an "interesting" career path from this guy.
Started at Data East as a pinball art designer for some of DE's best known titles as seen here:

A short vid below from the man himself on his background pertaining to pinball. Take note of the humility - World's Number One Pinball Artist, single handedly raised the bar for 1990's pinball artwork et al.
If you have some time to kill and need a laugh you can watch some of his other "motivational" vids but a word of caution that the underlying messages that he is promoting may cause cerebral collapse.
