PCB Roller Coaster is a screensaver for Windows (DirectX 9), featuring a Printed Circuit Board 3D model and fly-trough camera motion.
The screensaver is actually the same software package as ZofzPCB 3D Gerber Viewer.
In the screensaver configuration dialog, it is possible to select a color scheme, camera movement speed, etc.
The screensaver features my old demo board. It is also possible to configure it to display your own PCB.
To do this create and save .camset or .zofzproj file using the ZofzPCB 3D Gerber Viewer and a set of Gerber files. See for yourself how amazing a PCB can be when seen as a roller coaster scenery!
