About this executable study

Version 1.1 reuses the validated Composição #1 browser engine and adds the Applesoft rotation routine needed by this work. The principal form begins at a random position, color, and rotation, expands through successive SCALE values, and is followed by six independently rotated XDRAW overlays.

The implementation uses the original 529-byte COMPSHAPE table and models the Apple II ROM's fixed-point rotation method, including its 17-byte cosine table, fractional accumulators, and 64-position ROT system. Composite color, machine timing, and the Applesoft random sequence remain modeled for the browser. Version 1.1 adds axis-sensitive composite blending: horizontal and vertical artifact-color strokes are displayed continuously, while diagonal rotations retain their original pixel texture.
