Simple test of the classic maze drawing algorithm changed to a threaded pattern. This is a recreation of a program & idea my brother, Matthew, programmed long ago.

100 CALL CHAR(65, "2424FF0000FF2424")
110 CALL CHAR(66, "2424E72424E72424")
120 CALL HCHAR(1, 1, 65, 384)
130 CALL HCHAR(13, 1, 66, 384)
140 CALL HCHAR(1 + INT(RND*24), 1 + INT(RND*32), 65 + INT(RND*2), 1 + INT(RND*5))
150 CALL VCHAR(1 + INT(RND*24), 1 + INT(RND*32), 65 + INT(RND*2), 1 + INT(RND*5))
160 GOTO 140

The original maze drawing algorithm would randomly show left and right slants. See here for more info: https://10print.org/

Emulated with Classic 99, Recorded with default Cinepak codec.
