tornado/fw/txt/: tools for text conversion
...
txt2xbm: convert text to XBM, using ghostscript
stretch: resample XBM with rotation correction (x-axis only)
xbm2gp: convert XBM to gnuplot, taking into account rotation
plot: plot xbm2gp output
t: run all the above to display "TEST"

tornado/fw/tornado.c: add test mode indicating positive zero-crossing
...
Works sometimes but often produces false zero-crossings, particularly
if there are many chain "jumps".

tornado/fw/tornado.c: use LED_* to communicate with LED bar; update demo
...
Instead of a counter, which worked okay with 16 LEDs but is useless with
all 64 of them, we now show a filling/emptying bar. The update speed is
high enough that rotation results in about a quarter-circle pattern.
