Planetarium (2015)

Last May, Daniel Linssen made this pixel-art planet generator. 

I like the way that it embraces the explorability of the generator. Each planet in the simulator is capable of supporting life, if you can find the right temperature to adjust it to. Adjusting the planetary parameters gives you more of an investment in the outcome, turning your browsing into an active search.

The finding-interesting-planets aspect of the simulator lead to a small community of planet searchers.
