The Punk Nova font
This is an OpenType implementation of Donald Knuth’s Punk font.
Punk is a dynamic font, every time a glyph is requested Matafont draws
a unique instance of it. On the other hand, OpenType is static; glyph
outlines are drawn once and stored in the font and the renderer can not
alter those outlines. To emulate the dynamic nature of Punk, we generate
several alternate shapes of each glyph and store them in the font.
Alternate shapes are mapped to the base character using OpenType
“randomize” feature (rand), which tells the renderer to select
glyphs randomly from the list of alternate shapes.
Since 2010 was the 2⁵ anniversary of TeX, each lower case letter have 2⁵ variants, 2⁴ for each upper case and 2³ for the rest.
Unfortunately, the randomize feature is not widely supported (HarfBuzz supports it, as well as some other less widely used applications). In applications not supporting the randomize feature, only default shapes will be shown.
The original METAFONT sources were adapted to a more MetaPost friendly form by Taco Hoekwater et al.
The PostScript outlines of the glyphs were generated by MetaPost, a Python script then used FontForge to import the glyphs into an OpenType CFF font.
This font is distributed under the terms of Open Font License (OFL).
The MetaPost source has the following notice:

Font inspired by Gerard and Marjan Unger's lectures, Feb 1985
The regular punk files are part of TeXLive and in Metafont format. All errors introduced are ours. We also changed the encoding to unicode. In due time we might add a few more more characters. We still need to improve some of the metrics which involves a bit of trial and error. The font just covers basic latin shapes but in ConTeXt MkIV we add virtual composed shapes. There is a module m-punk.tex that implements this. This derivate is also used in mk.tex (mk.pdf) which is one of our tests for LuaTeX. We published an article on it in the MAPS (NTG magazine).
