For those of you who attended to the talk (thanks a lot for attending, by the way), you may find in Codeplex project DynamicDeepZoom all the source code we used for the example we presented, as well as the presentation (in Spanish). And for those of you who didn't attend, we are uploading it anyway.
Para los que asistieron a la charla (muchas gracias por su asistencia!), subimos al proyecto DynamicDeepZoom de Codeplex todo el código que utilizamos, al igual que el powerpoint. Y para los que no asistieron a la charla, lo subimos de todas maneras.
