Here's something I've been doodling with my brush pens for a while now. I'm getting to the point where I like it enough to commit some type work to it to see where it might lead. I'm pretty bad at brush pens — especially at getting thin lines out of them —, so have mostly low-contrast strokes to work with. Still, between the subtle modulation within the strokes and some local lightening through loosely-joined strokes, the style is workable for blackletter.
The working title of this is currently Komik Ohne, a tongue-in-cheeck bad German translation of Comic Sans. I'm calling this the blackletter equivalent of Comic Sans, in the hopes of making a little PR out of the latter's pop culture status. «Use Komik Ohne for job applications, scientific presentations, monument inscriptions, etc. — basically, wherever you would use Comic Sans!»
(I might switch to a more serious name later.)
