*** #1 Music App in 7 countries! *** Network of nodes makes novel sound. Each node has distinct tone. If you tap node, then the node is "excited" and make sound. Once the node is tapped, the node is ready to connect edge to other node (indicated by sorrounding circle). The excitement of nodes are spread via edges. Cycle of edges will produce interesting sequence of sounds. ***Unfortunately, this app could not run properly iPodTouch 2ndG or earlier due to hardware limitation. Best regards.***
