This baby toy model is made up of several objects. One for each ring and one for the main part, all parented to an empty and set up with rigid body. Not the most original brand name on this toy, but after all it is made in Blender :). The scene also contains a display setup with three light sources in a separate layer
Thank you! Guess I were a bit hasty towards the end. Anyway, I take your advice and have updated the model with a bit more joyful colors. I also added a rigid body system. (Sorry about my slow response time :).
Those colours are much better! I like the way that you have arranged the colours - sandwiching the primaries with their mixtures. The rigid body system is a nice addition.
It is nice, but it would have been even better in more child-friendly colours. Children are most attracted to the primary colours of red, yellow and blue. Other suitable colours would be other bright colours, like orange, pink, cyan, etc.
