Wright Window
A window built by dividing a frame with parallel lines. The story is not written yet; this is the board, to find out how it feels.
The square is your window, ten steps across and ten up. Full screen in the column fills the screen; the same word, or the Escape key, brings the page back. Before your first line, drag one of the small dots outside the sides to make the window a different size. Then press on any edge and drag into the pane: a line comes with you, parallel to the edge, across that one pane, and settles on a whole step when you let go. Lines never cross; they meet. Tap a pane to colour it.
Under Demo on the left, Wright divides the window the way Frank Lloyd Wright divided his, a few large panes and some narrow strips and small squares, colours a handful of the small ones, and shows the window by itself.
An experiment: the words in How this works and on this page are placeholders, and the window’s steps are in the board’s own unit, which has no name.
