My lovely wife got me this cool trigger set from ebay:
HSF Ultra Micro Pack Photography Trigger Sound Laser Lightning Delay Box | eBay
A laser trap trigger for catching wildlife/birds (going to try and photograph the hummingbirds at her mom's place next year) or doing water drops, a lightning sensor trigger to photograph fireworks and lightning, and a sound trigger to photograph things that make loud noises… not sure what I'll do with that one, but going to a firing range to try and catch bullets emerging from a pistol might be worth a shot (pun vaguely intentional). Also a delay box to make sure it snaps at the right moment, and of course the appropriate trigger cable.
And I just bought her a Pentax Q with the 5-15 lens for $150 from someone who just never really got around to using it.
