I built this back in 2010 to provide a prototype that could be used to test use cases and be used in usability studies. As a side project, I also took the Ghost concept and applied it to a WPF application by wrapping the UI around Ghost functionality.

Note: Rooler was not built by me. This was shared by another worker at Microsoft

• Create a prototype that allowed for different user flows
• Allow a developer to quickly obtain measurements
• Allow developers to draw on top of work and save
• Allow Usability Researchers to setup scenarios to test
• Allow Design to skip the redlining process
