I had a `good idea' earlier today. Diamond collector is a rather nice way of getting students to practise finding equations of lines. I think that it's the same resource type as Mathmo, but with a couple of nice advantages (more engaging, slightly distracts students from what they're doing so that they might develop more fluency). I wondered whether it might be possible to make a version of Diamond collector that allows players to use equations of circles too. Perhaps just circles, perhaps a mix of lines and circles (possibly those are different levels or something). We could talk about what form the equations of the circles should take.
Use http://mathquill.com/ for equation entry. From @vrn20:
