• (At least) 20 frames
• pre-calculated rotating cube loop.
• clean looping (data string never exceeds some finite length)

Running the example through xterm Tektronix mode (-t):

xterm -t -e "./ct.py --hold 100  <(./CTBASIC.py examples/CUBE.BAS)"

(partial cycle, the actual animation is smoother:)

Testing the datastring length to confirm it is bounded:

./ct.py -d <(./CTBASIC.py examples/CUBE.BAS) | cut -f2 | awk '{ print length }'

The minimum datastring length is 1, the maximum is 971.
