Silly topic. I'm quite the avid "gamer" and have been trying to merge my main hobbies little by little over the years, it hasn't been a very focused effort, or one with a clear goal or anything. It's just something that I sometimes think about and end up doing one small thing (like getting a wireless controller to manipulate more freely while playing a game, for example).
What I'd liken to see is really just someone beating a video game while incorporating juggling into the execution of the game, preferably by manipulating the input devices (damn, someone has got to be doing some crazy stuff with Wii nunchuks somewhere.) It has a big chance of just turning into a weird combination trick, though. But maybe the two activities can somehow make sense together? Would be really cool if it was in a performance.
I'm guessing other people must have done a lot in this field, somewhere, but I haven't seen much in the way of performing or such. Related stuff I do know about:
-Playing DDR (is played on arcade machine using feet) while juggling clubs. I think someone posted a video of Ben Thompson doing this. This is pretty much exactly what I mean, but it's basically just a nonsense combination trick. You might as well be playing [any game] while riding a unicycle?
-Reactable. Manipulation of objects on an interactive interface to create music? Pretty damn close to a video game where you actually physically juggle/manipulate to achieve something, but then, it seems really closely related to playing an instrument too. This might arguably be exactly what I'm looking for, though!
-Juggling flying drones. Manipulating objects which are in turn controlled by a computer https://www.youtube.com/watch?v=w2itwFJCgFQ This is super cool, but still distinctly different from what I'm looking for.
-I haven't watched his stream, but I suspect that BoBBo is sometimes juggles in his LoL stream (or is he a DotA 2 player?) Streaming might be a really good medium for performing this kind of thing, in any case.
-Not really video games, but somewhat related is solving a Rubik's cube while juggling, seen a few videos of this.
-People playing video games about juggling, there has been a few of these around. Also games not about juggling per se, but which incorporates some kind of juggling anyway, such as fighting games with air combos. Doing inputs isn't juggling when you're using normal input devices in normal ways, though, I guess?
-Finding ways to juggle in video games where it isn't mean to be a feature. I think I saw Elias Hedlund doing some stuff with the gravity gun(?) in half-life(?) way back in the day. Example: https://www.youtube.com/watch?v=PeWBPCFT-_U Again, about the normal input things. Maybe doing something like this while juggling the controller would make sense, though?
That's about all I can think of right now. I didn't take into account stuff where you don't actively make inputs to influence the juggling in realtime. No siteswap simulators, NPC jugglers in the scenery, or virtual juggling machines in minecraft as I feel it's pretty obvious that it would not be related to what I'm talking about, really. Although I can imagine that depending on how it was executed, things involving these can absolutely make sense in a performance of some kind.
