So, I finally have a good reason to start tinkering with Nerves! 
I’ve been asked by the student association to jamble together a Photobooth for an upcoming party. So, I want to take this opportunity to write a Nerves-application on top of a Raspberry Pi.
I already found the Picam elixir/nerves library to take pictures with the Raspi’s camera. What I am still looking for is a way to interact with a (touch?)screen from within Elixir/Nerves, because I’d really like to show the camera preview on there.
Should I just go ahead and use the Erlang Wx-bindings for that? Or is there a better way?
And is there already a way to read out touch screen presses from within Nerves?
