I do like futuristic looking demonstrations of technologies that will play a big role in the coming years. One demonstration that I found absolutely fascinating is a Photoshop multitouch image editing one. Working with small screens and a mouse plus keyboard combination is the current state of the art when it comes to image editing. It becomes problematic in a number of way including working in a team. It is also not natural to use a mouse to draw and edit images. Multitouch image editing uses a natural flow and offers a bigger detailed view of the image at hand.
