Okay, THIS is actually really cool. It's called “di:stage” and it's basically a setup for you to pose your figures however you want-- specifically your Figma figures. See, Figmas generally come with a base where you attach your figure to it by a partially moveable arm.
This product, an official one from Figma, lets you attach those arms into a base unit with a bunch of little holes in it, so you can put it where you want to. The theory being, of course, that you buy a whole bunch of base units and put them together to create a larger “stage.”
Looking at the above pic, it seems like one of the figures they're showing is attached via an arm that's attached to the base as usual but has a “claw”-style attachment at the other end, meaning that you could tentatively use this for non-Figma figures as well, as long as they're the right size.
Suggestion, Figma: make arms that are as close to universal for figures as you possibly can. Because if it's not hideously expensive, and I feel comfortable that I could put most of my figures (many of which are not Figma) in the thing, I would definitely buy some of this stuff. It looks like it's not going to be hideously expensive, it looks like each set (which comes with a base and a handful of attachment stuff) is ¥580 (about $6.05).
If you want to see some of the stuff in action, click any item here and it'll take you to a video. It's pretty cool beans. What do you think? Would you use it?
