They are best read as a historical gallery, not as a current browser-compatibility guide: Sam Deering’s SitePoint roundup was published on March 27, 2012, and updated on February 12, 2024. Read the SitePoint showcase.
Ten HTML5 and JavaScript experiments
The examples span several kinds of browser interaction. Some emphasize visual effects, others respond to a mouse or keyboard, and a few are closer to tools or demonstrations of browser performance. The roundup does not report controlled performance measurements across the demos, so the comparisons below are descriptive rather than benchmark results.
1. Canvas Sphere
Emil Korngold’s Canvas Sphere projects points from a 3D sphere into a 2D view using a small sprite 3D engine. Z-sorting and alpha motion blur help suggest depth and rotation, illustrating how a convincing spatial effect can be assembled from rendered points and visual cues.
2. Marbles
Marbles is a physics experiment built with the A3 WebGL Engine. The original roundup said Chrome was needed to view it; that is a historical instruction, not a verified recommendation for current browsers. Check the live demo and your browser before relying on it.
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
3. Noise Field
Noise Field uses Perlin noise to steer trails of particles. Moving the mouse changes their motion, while clicking randomizes the parameters, making the underlying movement both visible and directly manipulable.
4. Fishbowl
Fishbowl is a Microsoft browser-performance test: viewers can see how many fish their browser can run. Treat it as an interactive stress-test-style demonstration, not as a standardized comparison of modern browsers.

5. Sticky Thing
Sticky Thing centers on a simple physical interaction: throw an object and make it stick. Its appeal is in the immediate response between a gesture and the simulated result.
6. Breathing Galaxies
Breathing Galaxies generates JavaScript-powered hypotrochoid forms whose colors and diameters change. Keyboard input changes the shapes, and moving the mouse creates a new one, blending generative geometry with direct interaction.
7. Flower Power
Flower Power is a drawing tool that uses flowers as brushes and Bezier curves to form strokes. Rather than simply watching an animation, the visitor makes an image through drawing.

8. One Hour Per Second
This YouTube-created HTML5 page put video-upload volume into context with comparisons. In the article’s 2012 framing, one example translated the stated upload rate of one hour of video per second into 345,600 nyan-cat “nyans” in a day. That figure belongs to the historical experience and should not be read as a current YouTube statistic.
9. Asteroid Belt
Asteroid Belt overlays an HTML5 animation effect on a photograph. It demonstrates how an animated layer can add motion and atmosphere to an otherwise static image.
Rank #4

10. Graph Layout
Graph Layout presents an interactive force-directed graph. The layout itself is part of the visualization, showing how relationships can be arranged dynamically rather than displayed as a fixed diagram.
What the collection demonstrates
Together, the examples cover several distinct techniques and purposes:
Best Value

- Visual rendering: Canvas-based 3D projection, WebGL, and animation over an image.
- Motion and simulation: physics, particle trails, and changing geometric forms.
- Creation and interaction: mouse-driven effects, keyboard input, clicking, and a drawing interface.
- Demonstration and visualization: a browser performance test, a video-volume comparison, and a force-directed graph.
SitePoint author Sam Deering framed the collection in 2012 as “some of the crazy HTML5 and JavaScript experiments that demonstrate the performance of the framework in rendering a variety of cool interactive effects.” That is the article’s original characterization, not a present-day performance finding.
How to create your own HTML5 and JavaScript experiments
A useful starting point is familiarity with HTML5 Canvas and JavaScript. Begin with one effect or interaction—such as drawing a trail, animating a shape, or responding to a click—then add complexity only as needed. Deering’s article names Three.js and Paper.js as libraries that can simplify complex graphics and animation; these are source-era suggestions, not a current evaluation of the libraries.
- Choose a small idea. Decide whether you want to render an effect, simulate motion, make a drawing tool, or visualize relationships.
- Match the technique to the idea. Canvas can suit 2D drawing and effects; the examples also show WebGL, particle motion, and force-directed layouts.
- Add one interaction at a time. Decide what a mouse move, click, or key press should change, and make that response apparent.
- Try code-sharing resources. The roundup points readers to CodePen and JSFiddle as places to explore and share code.
- Test before reuse. An experiment that pushes a browser effect may not be suitable for production. Test its behavior and consider performance in the setting where you intend to use it.
For structured learning, choose an HTML5 Canvas or JavaScript programming book that matches the technique and experience level you want to build; the roundup does not verify a particular current title.
How to read the browser-compatibility notes
The roundup’s comments that most demos ran smoothly in Chrome and Firefox but not Internet Explorer describe the support context discussed in an article first published in 2012. They are not a current compatibility test. Browser behavior can change, and the Marbles Chrome instruction is similarly historical. If you want to try a live demo, check that demo in your present browser rather than treating the old notes as current guidance.
