In 2008 I worked for a company called Mod Systems, making a Flash demo for the Kiosk system they were building to sell music and videos for download onto devices.
Please note that this was not designed for deployment on the web, which is why there are no loader bars and why it may take a long time for the secondary swfs to load when you click on either the video or music icons.
Press buttons 1-6 to simulate hooking up a device or swiping a card. The checkout system works in the music section, but not video.
