Hi Desine_Guy - thanks for all your efforts so far.
#82 is my favourite and the one I will choose as my winner.. Thankyou!
There are still a few things I'd like to try before we fininsh though. Disregarding my previous note, can you:
1) Keeping everything else the same, try making the 4 dots a bit smaller in size?
Could you also try:
2) Keeping everything else the same, having an inner line linking the 4 dots (making this line the same width as the outer line)
See how we go!
