A while back I was tipped off about a tool from Microsoft called LightSwitch, and it looks like it has come out of Beta and is now an official product. So I took a quick look at it and was able to use it to easily create some alternative screens for Dynamics AX without a single line of coding. This is too cool.
If you want to see the walkthrough that I created, I posted it here on SlideShare: http://www.slideshare.net/murrayfife/creating-dynamics-ax-2012-interfaces-with-microsoft-lightswitch
