This looks interesting:
If you program microcontrollers like the Arduino, you should check out XOD and see how you like visually creating software.
The software is open source and currently, can target the Arduino or Raspberry Pi.
Some alternative visual programming tools:
– LabVIEW RT or Matlab Simulink – both very powerful, very stable, closed source and very expensive
– Scilab Xcos – powerful, unstable, open source, free
– MyOpenLab – enough power, stable, open source, free
Visual tools already covered on this blog:
