Novell Inc. commissioned The HyperMedia Group for a HyperCard stack
for the rollout of its first Mac product, NetWare for the Macintosh.
Kevin Millecam, then Novell's network-products marketing manager, said
he picked the group to do the project because "it was obvious they
knew their stuff like no one else."

The HyperMedia Group delivered a stack for the 1988 Macworld show in
Boston that featured several firsts, including font animation and
other "candyware" - items that tempt people to spend more time with a
stack.

"It was a revolutionary stack for its time," said Millecam. "Other
people were trying to do animation in HyperCard and other things that
The HyperMedia Group delivered for us." The stack caused a stir at the
show, and Apple's Jean-Louis Gassee used it in his keynote speech.

In this stack, a large butterfly flies across the screen, landing on
words and other graphics. Included are bonus tools for software
administration and a font animation tool for recording your own
animation sequence for the butterfly. The code is a great
demonstration of what could be created with HyperCard and HyperTalk.

Any Macintosh system that can run HyperCard. I am not certain the
minimum version needed to run the stack. I tested it with HyperCard
2.4.1.
