I'm trying to accomplish some animation with sets in Raphael, but even though an opacity animation worked, I cannot succeed in moving a set (or even a circle) around the canvas.
I found on the Web that moving a set should be done with setting translation, not x, y positions (as they may be different for each element in the set, and just x and y may not be enough for moving some elements), but it doesn't work for me. Nothing is moving, even though the animation callbacks are executed in time, as expected.
Up to this point, the best way I can use the following code is to see how the time is ticking (in the console)...

To move a set in Raphael, use:
I played with this a bit (and scanned through the source) and it looks like you need to specify the transformation in a form like
{transform:'M 1 .5 .5 1 15 25'}. Take a look at this fiddle to see some transformations.BTW, the transformations aren't working exactly as i would have expected, and I can't pretend I understand why... I am pretty new to Raphael and SVG. Anyway, I hope this helps move you in the right direction.
