Theme

Each row of the table is one letter. Five cells are five bits: a shaded cell means 1, an empty cell means 0.

Photograph the table from above so the whole grid is in the frame. The table is found automatically.

Alphabet

Highlighted symbols are extra characters for links (codes 28–31). An empty row, 00000, reads as a space.
