ere are some more UI designs for clients I served while I worked inside of American Systems and when I worked for Echo Eleven Media. I have done eLearning interface design for companies like Intercontinental Hotels Group, Wyndham Hotels, Delta Airlines and Morgan Stanley.
Most of the concerns with this type of work is maintaining the branding guidelines and still make it look good within your existing frame work. You are just skinning the eLearning player over and over and just changing some of the functionality based on each clients needs.
I've had to work in many different LMS's as well. Skyymap's and Echo Eleven Media's LMSs both were Flash based but worked in an entirely different way. It is fun and challenging to work with different learning management systems and figuring out their nuances. In the end you have to figure out what makes them dance and what provides the best learning environment for your end users.
