The LUCY is an excellent tool for teaching drawing because it helps students translate the 3-dimentional world onto 2-dimentional paper, so they can draw what they actually see. The LUCY can act as a sort of training wheel that accelerates and livens up the learning process.
Working with the LUCY, noticeable improvement in drawing can be seen in less than an hour. And these final results are achieved freehand—without the tool. The idea is to use the tool in a series of easy exercises that teach critical drawing skills the fast and fun way.
