Commemorate a special day/event in your life with the very stars that were overhead at that moment!
Enter the GPS coordinates (for help converting an address to GPS data use LatLong.net), date, and the time of day and I will use the Open Source project D3 Celestial to generate a stereographic projection map of the stars.
The map is scaled to to fit over a 4 coaster set and is available in the normal coaster materials.
Humanity has long gazed at the stars in wonder and amazement, capture some of that magic for yourself.
You can learn more about the different materials I use on the Materials Page!
