Tacky but interesting: this is a huge spider garden spike that I got at the $2 shop the other day. It’s a hand span across, and the connections between its legs and body are fine springs, so that when the spike is jolted the legs have an incidental movement. The best movement you can get out of it is a kind of drumming of the legs, where, on each side, legs 1 and 3 are in sync with each other, and legs 2 and 4 are doing the opposite. Then it has the right kind of action for a huntsman spider.
I have a couple of other insect garden spikes, a bee and a dragonfly (bought out of curiosity when I was working on making giant bees and dragonflies a few years ago). They are much smaller than the spider, with bodies about 7 cm long, and the wings are on double springs. The dragonfly has much lighter springs, and a much better incidental movement than the poor bee, whose springs and wings are way too heavy.
