The most recent version of protograf - a desktop tool to help you design boards, tiles, cards and boxes for your prototype - has just been released.
Quick blurb: protograf is a free, open source, cross-platform tool for scripting a design. It is not web-based and does not have a GUI, but offers sensible out-the-box options to get started on your design, while allowing a reasonable range of customization options to create neat and usable graphic layouts.
This latest version adds a new basic shape, called a "Band", and then allows both Bands and Rectangles to be customised and then joined together to create RaceTracks. An example can be seen in the attached image.
The online documentation for protograf is available here:

Please feel free to make suggestions or give any kind of feedback. I am also happy to help folks with developing their scripts.
