Saw this popup on Indiegogo. Basically it turns your 21" or 27" iMac screen into a touchscreen. Looks pretty cool. Here is the project link : http://www.indiegogo.com/projects/the-imac-reinvented Apparently it uses IR technology to capture finger position and is a lot more accurate than a normal touchscreen. There is no glass involved , also it seems to be plug and play - Here's a couple of quotes from the project page "How does C2T work? C2T utilizes infrared technology overlaid across the screen to enable you to control the functions of the iMac by touch. Using a glass free design coupled with our unique and patented "beam collation algorithm" technology the C2T has reinvented the iMac and how you will use it in the future." "Do I need additional software or drivers? No. C2T is PNP (Plug & Play) so it requires no additional software or drivers. Simply plug in the USB wait 10 seconds and your iMac will be touch enabled." What does everyone think, good idea?
