Hope these won't bore everybody but they are a challenge and as such good for honing my skills!
Dave suggested my geometry could be better - my only defence is that it is hard to get an interesting pattern and have enough pixels to upload. Maybe I have to make bigger oil shapes and get even closer. I've seen some pleasing shapes by other members who are not sharing their secrets!!! I didn't have an absolutely clear glass
so I've bought one today. The above image was taken in a glass with ridges as you can see but the pattern is interesting!!!
So many thanks for comments and votes - I don't mind constructive criticism at all.
I'll enable modifications as Dave suggested and see what other members can do.
