Ahead, a competitor for Prezi?

Worth a look at this new web-based presentation engine that has Prezi-like effects, Ahead.com:

Ahead is a web application that allows creative people to easily create and publish their visual work as online portfolios, web sites, galleries, and presentations – anyway they want.

We are a team of architects, designers, developers, and business people with backgrounds in the creative industry. Ahead originated out of frustration with the shortcomings of current tools for online collaboration and publishing because we don’t think they support rich media and visual creative processes and communication very well.

Inspired by the proven zoom and pan user interfaces.
