a recipe



Someone with more time on their hands than I, please animate the following
three sets of three rows of 38 ascii characters.

Each of the three rows of characters may and should superimpose; think of
an LCD grid like a cheap digital clock.

The movement should be grid snapped, one 'character' at a time.

"Roll" means move with wrap around in this context.

Each of the three sets (1, 2, 3) is three rows deep. Rows are labeled for
illustrative purposes only.

1. stationary or roll very slowly (W; W ~= .1 * X?) either direction:

    1234567901234567890123456789012345678
1a:
1b:                                 \   \
1c:             \                       /

2. roll X rows right per cycle:

    1234567901234567890123456789012345678
2a:  _ _     _  _   _   _   _
2b:                     _
2c:          _      _   _   _   _

3. roll Y rows left per cycle:

    1234567901234567890123456789012345678
3a:
3b: | | | | |  | | | | |   | | | | | | |
3c: | | | | |  |   | |   | | | | | | | |

The intent is produce, periodically only, the 'correct' juxtaposition (as
shown in the initial starting positions above).

Varying W, X, Y may produce interesting variations that juxtapose
'correctly' at different periods. Extra credit for attaching LFOs to W, X,
Y that juxtapose 'correctly' at a pleasantly (perhaps chaotic)  modulated
rate.

Extra credit for modulating within rows (ie, xA vs xB vs xC) in addition
to the basic assignment.

Monochrome is sufficient for first tries; it might be interesting to
color each set a different color.

Best regards,
 aaron
