I would like to use an iPad as a sketch board during some presentations. Idea is quite simple. I draw on the iPad and the people can watch it on the big screen. One way to do it its plain simple. Just connect a HDMI cable to the iPad from the projector and you're set. You can use any app you prefer for that.
The problem arises if you want to get rid of the cables. I do have a Mac, which can be connected to the projector, but where to go from there?
I would imagine to use the Mac as some sort of the Airplay receiver, but then again one would still need a special sketching app, which supports this setup. Or is there a native way to clone iPad screen over to the Mac?
Any help and ideas appreciated!
