ISBoxer runs on Inner Space, you've got it exactly backwards ;)
Most of what people have been sharing is ISBoxer related, like the [partial] keyboard and mouse overlay MiRai designed. Other projects people mostly keep to themselves, like for this "World of Workout" project -- http://www.twitch.tv/tehtsuo -- he needed to map the exercise machine outputs as game inputs. So to be honest I don't even hear about the vast majority of what people create on their own.
