Medford High School in
 glassblowing in England, he began his artistic career by blowing
art glass in
New Brunswick in the early 1970s.
The Demaine Studio, located in
 Miramichi Bay and later at Opus Village in
Mactaquac, was the first one-man glass studio in Canada,
part of the
 international studio glass movement. Demaine's pieces from this period are represented in the permanent collections of half a dozen major museums
 Canadian Museum of Civilization
 National Gallery of Canada. Since joining MIT, Demaine has begun blowing glass again, as an instructor at the MIT Glass Lab;
his newer work features innovative glassblowing techniques intended as a puzzle to his fellow glassblowers. 
Martin Demaine is the father of MIT Computer Science professor and
Erik Demaine; in 1987 (when Erik was six) they together founded the Erik and Dad Puzzle Company which distributed puzzles throughout Canada.
 home-schooled by Martin, and although Martin never received any higher degree than his high school diploma, his home-schooling caused Erik to be awarded a B.S. at age 14 and a Ph.D. and MIT professorship at age 20,
making him the youngest professor ever hired by MIT. 
The two Demaines continue to work closely together and have many joint works of both mathematics and art, 
including three pieces of
 mathematical origami in the permanent collection of the
Museum of Modern Art,
and another three in the permanent collection of the
 Renwick Gallery of the
Their joint mathematical works focus primarily on the
 mathematics of folding and unfolding objects out of flat materials such as paper and on
the computational complexity of games and puzzles.
Martin and Erik were fans of
 Martin Gardner and in 2001 they teamed up with
Gathering 4 Gardner founder
Tom M. Rodgers to edit a tribute book for Gardner on his 90th birthday.
Father and son are both featured in the movie  Between the Folds, a documentary on modern origami.
