I've cast my eye over Terry Blunt's excellent CoOrdinate program after
making it run on a Raspberry Pi/Full HD monitor. I can't figure out
what's causing objects to stick together (2 or 3 pairs sometimes with
gap) and sometimes a wobble (run CoOrdinate_FHD for some seconds to
see). When a moving object collides it then becomes part of the new
pair. A similar thing happens when the object is static.

The original program (MODE 9) had only 4 filled circles but I've
increased these to 30 - it still exhibits same problem. Any programmer
who would like to take a peek/fix then download from...

Information is located in a PDF book...

and CoOrdinate collisions are covered in section 5.4
