Vintage Computer Racing: Race 1 - Leibnitz Pi Estimation

I quite like the idea in here, a sort of inverse of a benchmark: instead of timing how long something takes, see how far it can get in a given time. In this case, summing a series that converges rather slowly:

It would be possible to do a 4-screen composite of several machines making progress on some task - maybe a graphical task. Maybe even print something wiggly and see which one wiggles most:

10 X=1
20 Y=0
30 FOR I =1 TO 999
40 Y=Y-X/16
50 X=X+Y/16
60 PRINT ;SPC(20+16*X);"*"
70 NEXT
