So, this is a very interesting concept by Marc Clifton whom I found on the codeproject.com. He is one of the senior members there and had been contributing to the site from a long time. I recently saw his article HOPE - Higher Order Programming EnvironmentProgramming Environment. Follow is an animation from this environment.
Also, a video demonstration can be found here on the YouTube.
Overall a very interesting concept. Kind of life the ideas of Alan Kay regarding object-oriented programming. So I look forward to studying, understanding and working with the HOPE concept in the future.
