The use of these materials create new avenues for architecture such as printing buildings. Professor Ronald Rael, the head of the project, stated that these materials and the designs they enable will require new IP protections — "This is going to require some IP protection for designs, so if you design architecture in the computer, you're protected, just as music and movies are." I wonder if he's ever heard of design patents?
egrep patterns are full regular expressions; it uses a fast deterministic
algorithm that sometimes needs exponential space.
