I was testing the TSP (Traveling Salesman Problem) art scripts (written for the Eggbot) to do a print on my Unicorn and this was the first image I came to that I thought would print well.

I compiled the TSP solver under Ubuntu and used GIMP to generate the point image.

For more useful information on printing TSP see:

1. Download Schmarty's excellent Inkscape plugin for the Unicorn: http://www.thingiverse.com/thing:5986

2. Import the SVG and scale it to the required size.

3. Export the design as MakerBot G-Code

4. Attach your Unicorn to your MakerBot/ToM and insert a suitable pen/pencil.

5. Print with ReplicatorG

Alternatively use the provided G-Code file, it will print a 70mm x 70mm version of the design on a ToM with a Unicorn. Take note that G-Code files are machine specific so may behave differently on different machines and firmware versions.

Note: the G-Code has several pen-up/pen-down commands throughout it for some reason, there is no travel done during these movements so they could probably be removed without issue, not sure why they were generated.
