I could only get it to 11 lines....

SCREEN 13
amp = 10
DO
r% = (r% + 1)
IF r% = 200 THEN r% = -120
FOR i% = 1 TO 360
PSET (((i% + amp) * SIN(r% * 3.141593 / 180)) + 160, ((r% + amp) * SIN(i% * 3.141593 / 180)) + 100), (i% MOD 255)
NEXT i%

Taken down to 8:-

1 IF amp = 0 THEN SCREEN 13 ELSE CLS
2 amp = 10
3 IF r% = 200 THEN r% = -120 ELSE r% = r% + 1
4 FOR i% = 1 TO 360
5 PSET (((i% + amp) * SIN(r% * 3.141593 / 180)) + 160, ((r% + amp) * SIN(i% * 3.141593 / 180)) + 100), (i% MOD 255)
6 NEXT i%
7 WAIT &H3DA, 8
8 GOTO 1
