When the half-angle blocks were first introduced I thought I would be the last one to produce an old style or transistional sans-serif typeface. Looking through the gallery, I still don't see any attempts. Creating a serif font with blocks is very much a square peg for a round hole, but I enjoyed the challenge. I tried to emphasis all the minor details, like angled stress, or the bottom terminal of the lowercase b. I spent a lot of time on this months ago, but after a while, just lost the drive to complete all the characters. Maybe you're up to the task.
