Fissure has been our client for a long time now.  This version of their site was designed with content management and blogs in mind.  Eventually we added an e-commerce piece that allows students to sign up for their courses or purchase their simulation software.

We have collaborated on two additional projects with Fissure.  One is currently being used internally and helps them manage aspects of their business.  The other was a custom application designed for one of their clients as online training.
