Nice idea, but not very revolutionary. I mean, we already have Processing, which is the same but with time included, and which has significantly more interesting efforts in its gallery, if you ask me. I'm not sure what these people are trying to achieve - if it's to get more people into procedural graphics, an (even) more accessible set of tools would be warranted. If it's to create splendid graphics, better tools would probably be warranted (though admittedly I've only checked 10 pictures or so).

On the programming-a-picture front: I always thought that this one [1] is particularly impressive (4 kilobyte Windows executable; zip includes a jpg for if you don't run Windows)
