As a player: What's the lag? Does it depend on the game and the gesture?
As a developer: I'd like to implement a "game" which would be ideal for Dynamicland (tens of cards with ID stickers on the corners), but this might be a simpler platform to set up and use. Would that be possible with the board as sold?
Also curious about latency. In the past I've worked around latency using video sensors for high-bandwidth high-latency features, then literally glued a contact mic to my interface to get low latency tap detection. How does the Board hide latency?
