New iOS app "Waking Mars" is a game about gardening, botany, and ecology, which sounds boring -- especially if you're about my age, and your primary school teachers tried to get you to learn about ecosystems via some clunky games with Oregon Trail-level graphics where you controlled the number of fish or ducks or some shit and then watched the population spiral out of control. That? That was boring. THIS IS RAD.
(Full disclosure: The designer/company founder is a friend of mine, which probably obligated me to buy the thing, but did not obligate me to stay up until after 1 a.m. playing it.)
