One of the coolest demos I've seen out of Ink N' Switch in while (tbh, it's seemed like they were really cooking for the year or so).

Unfortunately, it seems they live demo they published is missing a number of the demos they featured in the talk (and its unclear how to do your own things), so it's a little hard to evaluate this more deeply.
