I recently did something called a Lightning Talk to my work colleagues about the ultimate basics of procedural level generation. I’m scared of, and terrible at, doing presentations, so I volunteered because I need to learn to face my fears. (Be bold, etc.)
A Lightning Talk is when three or four people do very short, five-minute presentations about Something Cool — so I figured that, since I kind of care about this stuff, at least my enthusiasm would shine through if my tongue refused to cooperate (it did).
This was written as an introduction for absolute beginners, because nobody at work gives two figs about game technology (except me), so it should be interesting enough for mildly technical people with a passing interest in the area.
