This is a most excellent design. The only critique I would have is that in Calvin and Hobbes it is called a Duplicator, though I can understand why you put clone machine. If this went up on teefury, I would buy it.
If you could figure out a way to emulate the line variety in Calvin & Hobbes this would be fabulous. As it is, it feels a little flat, particularly the tall one. Maybe more overlapping lines?
Why does everyone sound so sophisticated here.....minus 2.. Anys, this IS a great design! I get that Calvin and Hobbes feeling straight! Tho you're my competition I shouldn't say this.... ahah
Sorry I don't have anything more productive to say.
oh i see it now never mind
