SassMe is a tool for designers/developers to help visualize SASS color functions. Inputting an initial color a designer can adjust it with the sliders and then grab the color function for use in their stylesheets. This was the first lab project I worked on for Arc90.
The original idea and prototype for SassMe was put forward by Jim Nielsen and the UI was fully blown out by Matt Quintanilla. I took on porting over the SASS color transformations to CoffeeScript and implementing all of the client side JavaScript to drive the application.
