Q: I just learned about this very cool animation tool, QuartzCode, that can make your online content more engaging...but it is MAC only and I am a PC user. Is it something similar to Quartz Composer in Windows?

A: QuartzCode is awesome! vvvv is the closest to it on the PC. There are many other animation/visualization/simulation/Web Rapid Prototyping tools that you can borrow from the music and advertisement industries such as Magic, Spout, resolume,  etc. The Udemy course is available to teach you how to create mobile and web interactive prototypes and designs with interaction and animation with Quartz Composer. Sounds like a good investment and fun. Check this forum for more.
