Hi,

I’m writing a sketch where I want many small particles to be attracted to large central particle, this is working.  
However I also want all small particles to repel from each other at the same time.

I’ve tried a couple of things and am getting erratic results.

here’s the: [https://codepen.io/jmean/pen/Eebzvq](https://codepen.io/jmean/pen/Eebzvq) if anyone’s willing to give me any pointers.

Thanks
