One relatively recent example that could be compared to the concept of teletext art is Eboy's Peecol. The equivalent font set can be seen as a webbificated, modernised version of teletext design. Taking the idea of pixel by pixel design on a small, monotone canvas, each letter corresponds to a 'body part', upper half or lower half. The parts can be combined in any way possible to form whole characters. In particular, the ones from the 'play' variation of the typeface can be likened to pixellated video game characters in their minimal, restricted approach.
It is very similar to Eboy's other work, which generally centres around the concept of low-resolution art; grid art; pixel art. Summarised, the canvas used is a 'shrunk down' version of the one used on teletext.
