Grid Cipher
Each row of the table is one letter. Five cells are five bits: a shaded cell means 1, an empty cell means 0.
Read a drawing from a photo
Photograph the table from above so the whole grid is in the frame. The table is found automatically.
Green cells were read as shaded. Tap a cell if it was read wrong.
Drag the four red dots onto the outer corners of the table.
Mark the shaded cells
Encode a word or a link
Copy the table onto paper and shade the same cells.
Alphabet
Green symbols are extra characters for links (codes 28–31 were unused). An empty row, 00000, reads as a space.
