Micro-sites are typically dynamic and compact web locations which are dedicated to a specific topic, product, or service. They can either be embedded within the page, or hosted separately.
We recently completed work on a micro-site for Licor Biosciences' digital mascot "Photon". The site was built in Flash, and uses coded animation for easy updates and changes.
See the result. In this example we started with a simple proof of concept to show that we could create the 'x-ray' effect, then, taking feedback from Licor's project manager, we completed the application. The resulting page is a perfect example of effective implementation of a micro-site.
