Some reviewers miss the point of this kind of software. If you want to make canned music, certainly get a Casio. Mona Lisa may be a poor example. The idea is (or could be) to investigate the translational perceptions among different senses. There are many software applications that do this, some being used professionally. Look into MetaSynth, for example. RGBM is not anything close to MetaSynth, but it's creative and...free. The developer should be encouraged to continue this work and make it available to those who appreciate the effort.
