Dot grid (புள்ளி)
Dots take the colour you picked. Lines you already drew stay where they are (Undo brings the old dots back).
Floor, page and files
Gestures: tap with two fingers to undo, three fingers to redo. (Web pages can't see the Pencil's own double-tap, so use a finger tap or the round button at the top-left of the floor.)
Open takes a kolam file from this app, or an SVG you drew in Inkscape: its dots and lines become a kolam you can replay as a reel (lines in the order you drew them).

It uses the colour you picked. Move it later with ⬚ Select.
