Great. I think you are right. Both in purple is better.
Nope. The small one does not have to be a perfect square – although it would be cool, if you provide a file that is – just add a bit of white space on the right edge - this makes it easier to use it on the forum (resizing)
The small ones you added are good! Only problem is, when it gets really small - 'CIRCULAR CITY' is not readable anymore. Any idea how to solve/improve that?
Not saying this is better – but maybe you can test something like this?
Update: Ah, just returned to this page. I think it is good enough. So, job done. Thanks Sam. Good job.
