Apple has a great mailing list and Q+A page that have been extremely helpful. The user community seems to be very excited about the technology and they put together some good resources at Quartz Comps and Quatz Wiki.
This is very exciting news unfortunately there are some other considerations. Quartz obviously will only run on Macs. That means our elevator signs could be switched from a DVD player to a Mac with a minimal investment but our WatchOut Sign system all runs and relatively high end PCs and could not be transitioned without a significant expense.
That means our way forward for the large Hennepin Projection would be to use Quartz to render movies and send those quicktime movies over to the Watchout computers to play. That could work fine but I am in the middle of diagnosing some problems where the Watchout software doesn’t always recognize changed content.
There will obviously have to be some more discussion on our part and more testing before we will have a plan to fully drive our signage system from our database.
