It looks pretty interesting. It’s a much, much nicer package than my home-made personal project, with a bunch of nice quality-of-life details.
Mine isn’t really designed for light painting… it’s designed for lightsaber use. In some ways, they’re pretty similar, but in some ways they take opposite approaches. Like instead of having a “momentary off” function, mine has a momentary overdrive function. It’s used for saber clashes and pretending to reflect blaster bolts. Also, instead of optimizing for what looks good in a long exposure, it’s more optimized for what looks good during real-time viewing. So there’s a pretty good chance mine won’t look very good on camera… but I’m hoping to find out anyway.
