FriezingWorks is a freeware HyperCard stack which creates friezes from what you draw using the seven frieze groups. It has two purposes. For those interested in transformation geometry, it can be used to demonstrate and/or explore the seven frieze groups. For people who aren't so mathematically minded, FriezingWorkz can simply be used to make nice frieze patterns for use in borders or other artwork. All you have to do is draw a base pattern and choose which frieze group you'd like to use for the frieze - FriezingWorkz adds extra black pixels to make sure the pattern has the required symmetries, and then makes the frieze.
