If you have seen my laser pointer video, or browse /r/osugame, you may have seen the capacitive keyboard I have been working on. Rather than using mechanical keyboard switches, there are touch-sensitive metal plates. It is similar to geckogates's metal plate input device, but does not require you to attach wires to your fingers. It is ultimately up to personal preference, but you might find streams to be easier when you don't have any actuation force or key travel.
