TelidonP5

TelidonP5

TelidonP5.js allows NAPLPS vector graphics files to be displayed in a browser using p5.js. Its companion encoder/decoder library naplps.js can also be used independently.
[ See an example ]

Background info:

August 15th, 2018 marked the 40th anniversary of the Telidon vector graphics workstation, launched in 1978. The Telidon hardware was discontinued in 1985, but its file format, standardized as NAPLPS, thrived and remained in wide use throughout the BBS era, until the mid-1990s. Thanks to its exceptionally small file size and limited animation features, NAPLPS can be seen as a technological ancestor of the animated GIF and the Flash SWF—a new artistic medium that could be both produced and distributed on the same machine.

From 1982–1985, members of the Toronto arts org InterAccess used Telidon systems to produce an ambitious series of interactive BBS-based artworks in the format.
