This from a new TIGHAR member:
Hello TIGHAR people:
I thought you might be amused to learn about my computer game with a Stargate theme, that runs on Apple Mac-OSX platforms that is free and OpenSource software:
https://sourceforge.net/projects/adagate/I am attaching an image from its first beach scene, where you might be able to just make out the large SOS in the sand and the nose of a Lockheed Electra in the surf. If you download and run the game, be sure to look up in the sky before leaving the island...
I am a retired mathematical modelling and simulations engineer that has helped to make the B2 stealthy. I'm considering the possibility of converting the island from my game into a more realistic simulation of the Nikumaroro atoll neighborhood, perhaps using digital terrain elevation and/or satellite imagery, if I can figure out how to get such data.
