Here we have a filled-counter pseudoserif pseudostencil that is also an IVO design at the same time!

Design Rules: 1. Internal negative spaces of glyphs must be filled such that a 0. 5-brick-wide void exists between the filled space and the glyphs themselves. 2. When a glyph's horizontal line intersects with the filled space created by Rule 1, both the filled space and the line will be broken. 3. Vertical lines may only connect by two tapering curves or by the implied connections created by filled negative space. 4. Filled negative spaces may only join with the outer perimeters of glyphs. Any part of the outer perimeter of the open parts of letters such as the underside of the circle of "g " is considered valid for this rule.
