Hi Don't know if this is pie in the sky but ... I have 60 kids coming to a conference each equipped with an iPad. I would like them to 'sign in' by putting their name and drawing themselves on their ipad and logging on/submitting to my ipad/mac. I've found an app called Socrative which does the same kind of thing - each ipad can log into a class and then submit text/answers i wondered if it was possible to do similar but submit graphics? My ideal end result would be a checker board on the main screen/display of all the faces signed in/submitted.
