I was working on the assumption that I would be able to use two laptops in order to project both onto the hanging shapes and the wall behind. However, I'm not allowed to borrow the extra one from the college, cos I'm apparently not the right kind of student. I now have to spend money on a solution that probably won't work, or even more money on something that definitely will work. I won't bore you with the technicalities, but basically I need a gadget that will allow me to output two different sources from the same laptop.
The cheaper option will mean I have to have a setup like this, actually physically having to mask the projectors off with card or something, which will be virtually impossible to set up without me wanting to kill something...and I'm not even sure it's possible.
The expensive option would be sooooo much easier and would be guaranteed to work - Matrox DualHead2Go. I have a decision to make.
Edit: I just got my loan through. What's a hundred pounds these days, eh? I'll try and sell some more videogames to cover the cost. It better be worth it though...
