I'm doing an Flash interactive - one screen is a touch screen and one screen is a overhead projector.
On the touch screen a user has the option to change the colour of movieclips - once the user is happy with the colours the results need to be displayed on the overhead projector (i.e. on a second screen)
Whilst a total solution would be perfect I'm just looking for pointer in the right direction please - preferably using actionscript 2 (if possible)
I'm assuming you are intending these to be 2 separate SWF's? Take a look at use of LocalConnection. This will allow you to pass data between both SWF's.
