The Crocodile ICT player lets you create and modify sequences of flowchart instructions, which can control on-screen characters or animations.
Based on our programming and control software Crocodile ICT, you can use it either on a whiteboard, or on individual computers.
The best thing, though, is this: the Crocodile ICT player is completely free, and once you've got it, it's yours to keep. Download it here:

We are planning to produce a similar style of player for Mac OS X, though this will take some time. (The full version of Crocodile ICT is Mac compatible already, but making the Mac player is part of a wider revision of our user interface to optimise the Mac experience - hence the delay.)
