Flowol was released in 1995 initially for Acorn RISC OS computers. It built on the Trol and Montrol products that we had for the Archimedes and BBC Micro. Mimics were first added in Flowol 2 about a year later.
I think you are confusing the two Logicator products, the Soft System you show appears to be from the Logicator software which supports control boxes, not the PIC Logicator (now called Logicator for PIC and PICAXE) which is a separate product targeting PIC and PICAXE. Flowol and Logicator are entirely different products, independently developed.
Clearly the pertinant feature for readers here is that Flowol now supports the Arduino and so provides a programming option for Arduino users.
I am not an expert about Logicator, but some of the main distinctive features of Flowol 4 are:
1. Flowol has a straightforward user interface for building the flowchart: lines automatically route when drawn, multi-stage undo/redo.
2. Flowol supports a wide range of control boxes (e.g. the new fischertechnik ROBO TX) and microcontrollers (e.g. Arduino and PICAXE) all from the same program.
3. Flowol's mimics use 3D animated graphics giving a realistic simulation. (I believe that Logicator uses either 2D graphics or video clips).
4. Flowol supports advanced features such as multiple mimics and interfaces.
As always, you should try for yourself. Flowol 4 is available for PC and Mac, details can be found here: http://www.flowol.com/Flowol4.aspx
