That's actually pretty impressive, good job! Should I use my phone flash to achieve better results?
Thanks! Yeah, the phone apps that do it turn on the phone's flash and it works much better - but I can't find a way to do that from JS. It seems like one of those things that's in the pipeline but hasn't made it in just yet.
