Web developers and designers gathered in Las Vegas last week for the 3 day MIX10 Conference. The first day began with presentations and demonstrations of the Windows Phone 7 developer platform in keynote speeches by Joe Belfiore & Scott Guthrie of Microsoft.

Microsoft BizSpark company Graphic.ly brought Marvel characters Spider-Man, Iron Man and others to life with its interactive digital comic book reader, using hardware-accelerated video and Silverlight’s Deep Zoom feature to pan and zoom across high resolution images. Graphic.ly also demo’d its online marketplace for comic books and social networking features for comic book fans to share their reading experiences.

Seesmic introduced a plug-in architecture for its Twitter app and showed how it could be used to add Bing maps to geo-coded tweets. Developed with Silverlight 4, Seesmic’s app will run on Windows Phones as well as on Macs and Nokia devices. Seesmic also hosted a Seesmic Plug-in Developer Meet-up, sponsored by Microsoft BizSpark. One audience member had already built a plug-in and demo’d it at the Meet-up.

The second day focused on Internet Explorer 9, introduced in a keynote by Microsoft’s Dean Hachamovitch. Microsoft Researcher Bill Buxton gave a presentation on Natural User Interface design. Michael Comperda, Director of Technology for the BizSpark company Curse, presented Curse.com - the go-to site for massively multiplayer online games. The Curse.com development team was on hand to meet with game developers and its fans from The World of Warcraft and The Hammer of Resistance.

Julien Codorniou hosted the MIX session “Software Entrepreneurs: Go Big With BizSpark and WebSiteSpark” on Tuesday explaining the benefits of both programs for early stage startups.
