A semibold Gongclonker made to the same specs as the original - 5x5 with no wasted matrix.
Coquette Dynatype by bugmenot666 is one of my favorite fonts. It has an exotic look while being very readable and regular.
With Dynatype Z I tried to take the exotic aspects further without changing the core design too much. The lowercase got some alternates, too!
An unconventional way to construct 5x5 pixel-based font using nudging facility to give an effect of distortion. Aaand yes, it's readable at pixel size.
