Impressive curves!

@Yautja: This work is based on my zikkurath font with some suggestive changes, but with many glyphs intact (don't worry, I think it's why the Clone button was made). I'd like to see how it progresses.

@elmoyenique I see, credits to you as well! I wonder why this doesn't show up as a clone.

maybe you cloned it into a different font and copied each individual glyph over to this one

Still, almost every single character has been altered in some way with the addition of lowercase. Great job @R.Mutt!

@R.Mutt: You admitted that RM Zeppelin is a clone of zikkurath eYe/FS. For some unknown reason, your font doesn't appear as a clone, but as an original. Your font is not a simple copy of Elmoyenique's work; you added your own creative parts and made it different. Needless to say, both zikkurath eYe/FS and RM Zeppelin are heavily inspired by Bauhaus fonts such as ITC Bauhaus, P22 Bayer Universal, and other works. And it is totally fine. My suggestion to resolve this situation is two-fold. 1) Keep your font public and redesign the special characters which were copied from Elmoyenique's font (# % & @). 2) Change the licence of RM Zeppelin to allow cloning (Creative Commons Attribution Share Alike). 

I feel a sense of gratitude and respect for Elmoyenique, who shares his work and allows others to learn from and build upon it. And so should you. Give him proper credit.

@R.Mutt: Thank you for your quick response. You did the right thing. I had a similar incident back in 2009 with my Karyotype font. That dispute was quickly resolved to everybody's satisfaction. I like your work. You seem to be an honest and talented guy. The Bauhaus art movement began in Germany. It's part of your cultural heritage. Don't rush to alter the special characters. Redesign them with patience and creative bliss.
