Don't see any signs of third party touch screen add-ons, such as a platform under the monitor stand or a custom edge.
"Since this originates from Dreamfield.se, a group that works on HD post-production (note their about section: “Dreamfield are working with any aspect of post production and the main body of our products are made in-house.”), I’m now 99% sure this is a fake." @http://www.sampletheweb.com/2009/06/14/iphone-os-running-on-...
