I'm not sure what you mean by more. Visual programming was explored a lot and became a popular approach for building non-standard interactive multimedia applications. I think the most famous and inspirational piece of this kind of software is Max/MSP which started as an interactive computer music environment (created by academic) and evolved into multimedia processing/generation powerhouse. It's commercial and proprietary software but it has an open-source "cousin" called Pure Data. Both applications were created by Miller Puckette and his creations inspired a lot of more or less similar systems. One worth noting is vvvv. It doesn't have musical programming roots and uses some unique and really powerful concepts to make graphics programming easier. http://vvvv.org/documentation/of-spreads-and-slices http://vvvv.org/documentation/of-spreads-and-slices Also it's a very pragmatic system which is built and maintained by people who do really cool and sometimes complex projects. http://www.meso.net/vvvv http://www.meso.net/vvvv
