Thank you everyone for your kind comments on my attempts at some graphic art
@Notes_Norton I think I'm with you there, but the circular one is kind of based around the idea of a synchrotron, which is also circular and I have been using a version of the circular logo for twenty years now. I used to use this one:-
But it is so old now, and, in its animated form, too large for most forums to use as an avatar. If you look closely there is a red and yellow sphere spinning in opposite directions inside the text.
The straight version was created specifically for my Bandcamp page as the circular one would have been much smaller in the rectangular space provided.
cheers
