Three small experiments about what a letter does when one of its properties is put under the cursor. The first one also sits at the top of this site.
A single g from a variable typeface, subset down to that one letter so it weighs 1292 bytes. Moving sideways runs it along the weight axis, moving up and down changes its height, and the distance from the centre of the frame decides how much of the field breaks apart into magnifying panes. It stays clean until something moves.
The same letter can be a surface instead of a subject. One S repeated across the frame: a thin stroke stands close and dense, and as the stroke thickens the letter shrinks and gets air around it. One number governs both, so the relationship cannot drift apart.
A hundred typefaces, one for every letter. Each letter gets its own face, size and shift, which is how a note cut out of newspapers looks. Click to set it again. The text can be rewritten, up to twenty four characters.
