I blogged a while ago, about the fact that I was speaking at a conference in Malmo, Sweden, regarding new interaction techniques, focussed on multitouch technology.
The presentation and the video are now online and can be found at: http://www.businesstobuttons.tv/webtv/89.html

Big thanks go out to colleague Pawel Solyga (Software Engineer at NUI and one of the co-founders of NUI Group) for helping me putting together this presentation.
