A considered starting point.
Details you can put to work.

Canvas background of drifting paper dots that keep away from headings, text and media. Controls for density, speed, colours, content margin and avoid selector. Pauses off screen and respects reduced motion.

A cloud of dots that moves between seven built-in shapes. Change shapes automatically, by click or tap, or through a window event. Controls for dot count, size, colours, timing, speed and selected shape. Includes offscreen pausing and reduced-motion handling.

A stack of paper sheets that grows with a number sent by a custom event, for example from the EffortCalculator. Controls for sheet size, colours, label and event name.

A strip of paper cells that builds a skyline over time; visitors click to drop a sheet. Controls for autoplay, interval, cell size, colours and caption.

A small burst of paper pieces on every click or tap, inside its container or page wide with a fixed canvas. Controls for colours, intensity, lifetime and an ignore selector for forms and links.

An overlay for existing images or videos that adds paper fragments at their corners. Controls for media selection, tile size, intensity, reach, speed, colours, scrub behaviour and touch pulses. Add it alongside the target media; it does not replace or wrap the media element.

An animated demonstration of a paper stack being organised into a three-column table. Controls for document count, labels and the three column headings, timing, autoplay, font and colours. This is a visual demo, not a document-reading service.

An interactive calculator with sliders for tasks per week and minutes per task that shows yearly hours and cost. Controls for labels, hourly rate, currency, locale and colours. Sends the result as an event for PaperStack.

Cards fly from a loose pile into an ordered grid, on click or autoplay. Controls for card count, columns, stage height, interval and colours.

A canvas animation that walks through named stages, for example Understand, Check, Expand. Controls for titles, numbers, tick, speed, fonts and colours.

Seven numbered building-block tabs with a title and text panel per tab. Controls for labels, text, numbering, colours, corner radius, font and text sizes. Includes optional autoplay and window-event input and output.

A muted looping video with poster image, lazy loading and a still fallback for visitors who prefer reduced motion. Controls for sources, poster, fit and radius.

A static image block with controls for the image source, alt text, height, aspect ratio, crop, focus, corner radius, loading and background colour.

A custom dot-and-ring cursor that follows the pointer and responds to selected elements. Controls for size, colours, speed, selectors, labels and native-cursor hiding. Disabled on touch devices and when reduced motion is preferred.

A hero background of blueprint grid dots that react to the pointer, clicks and holding or dragging. Controls for grid spacing, density, colours, opacity, content clearance, speed, target and avoidance layers, and event prefix. Includes offscreen pausing and reduced-motion handling.

A pinned text section whose font weight changes over its own scroll track. Controls for text, start and end weights, track length, maximum width and colours. Uses a fixed font stack.

Animated rolling numbers for statistics, using a fixed monospace font stack. Controls for value, prefix, suffix, label, number and label sizes, colours and duration.

Three built-in technical SVG drawings: Elevation, Region map and Portfolio map. Controls for motif, animation mode, place names, highlight, caption, colours and duration.

A reading-progress bar fixed to the top of the page. Controls for fill colour, thickness and top offset.
