I specially like how different variations and ideas can lead to similar results.
The way I've done it is also kinda unusual, I'm sending you the params
And of course, thanks for the mention in the AC
Thank you so much for your comment, I'm glad you like it
By the way, your help, indirect or not, was really valuable for me.
