This is my work Tesseract Generator redone in fine point... I think it is a genuine improvement over the pencilled version and it was a great exercise to boot.
I probably should have taken on something a little less intricate for my first inkwork in a while.. this took a lot more time that expected, but I think it paid off. To date, I don't think I've actually ever seen a tesseract generator... so I guess that is something. lolz.
I hope you all enjoy it!
