I’m really enjoying giving a control panel of sorts to the end user and letting them control the physics rules of their canvas. Let’s add more motion to it by applying a jitter to the velocity of each dot. This is similar to earlier, when we first started animating by applying a random number to [...]
I always want to give the end user (at least some) control of how they view and interact with data. Earlier we gave users control over gravity. Here let’s give them control over the canvas edges. Rather than having our dots bounce on the edges of the canvas, lets have them wrap across to the [...]
Earlier we worked on making all the dots draggable, but what’s better than simply dragging dots? Let’s set up a way to throw the dots! Now as we drag it we record the positions and use that to calculate a new velocity. Then when a dot is dropped, it will have a trajectory to follow [...]
Here is an update to allow the end user to create more dots. A good way to do that is to just let users click on the canvas, and if they click a dot, drag it, if they don’t click a dot, create a new dot at the point of click. I moved the dot [...]
Now that we have gravity we’re really seeing some natural looking movement. Yet, it’s still missing something. In the real world we have friction or drag (or even air resistance) on everything. Without this friction it’s like these balls are moving in space. Even when they bounce on the walls they don’t loose any velocity, [...]
Bret really hits the nail on the head. This is something that has been bothering me for a while but he put so many words to it (and pictures). A must read for any interactive dev-signer. Are we really going to accept an Interface Of The Future that is less expressive than a sandwich? Link: A [...]
Adding gravity! Here we’ve adjusting the y velocity in every frame with the force of gravity. It’s fun to play with options and see how they are affecting the animation and the physics, so I’ve also got a checkbox that will toggle gravity to either a vlaue of 2 or 0. interactive physics animations via [...]
Go watch/play at: http://www.baroque.me/. Very cool interactive musical visualization by Alexander Chan, also behind the Les Paul Google Doodle and Conductor. I’m always a fan of visualizing music and this goes even further in that it creates the music. It’s like he’s created his own digital instrument.

Well, the last iteration was fun, but the animation went so quick. Now we’re going to do something to contain these dots in our canvas. Let’s have them bounce off the edges of the canvas. We’ll multiply the velocity by a bounce variable. This will reverse the direction the dot is going. We’ll have a [...]
Now that we have our framework for animation we can make things a bit more fluid. Let’s use a velocity to update the positions or coordinates of each dot rather than just throwing random numbers at them. We can then adjust the velocity or rate of movement and it will be a much more natural [...]
Zero images is something that always gets me excited, I really like these arrow button styles! I like the css used more and the hover/active states too, nice css3 transitions. via Adobe-like Arrow Headers | CSS-Tricks.
After playing with the settings in my experiments I found a few settings I liked and wanted to develop further. The first was snow! An added bonus I was able to work on a project just for the holidays and used much of this code in it! I looked around the web and saw a [...]
Microsoft has a new line of TouchMouse. They have a campaign to cooinside with it called the Art of Touch and have invited a few artists to participate and more to drive interest with free shwag! Basically that boils down to me having a to give away! So go play with the app and link [...]

Here’s a great article about the process of responsive design & mobile first design and how to practically use them both in a project. This site is a proof of concept for many of the ideas described in Rethinking the Mobile Web or (Mobile First Responsive Design). via Yiibu – About this site….
Here’s a great tool to make responsive grid layouts. Thanks to Erskine Labs! Introducing Gridpak | Erskine Labs.
Here’s a great little script I found useful today as I was working on having dynamic effects applied to javascript via canvas. “The canvas element provides scripts with a resolution-dependent bitmap canvas, which can be used for rendering graphs, game graphics, or other visual images on the fly.” Thanks to the canvas APIs I was [...]
A great css developer helper script from Fred. CSSrefresh is a small, unobstructive javascript file that monitors the CSS-files included in your webpage. As soon as you save a CSS-file, the changes are directly implemented, without having to refresh your browser. When you’re coding a website, nothing can be more frustrating than having to switch [...]
I'm Evan Mullins. I'm a web designer and am very interested in the intersection of art & technology, user experience, and interactive design. I like contributing to make the web incrementally a better place. I love simultaneously solving problems & making things aesthetically brilliant. circlecube is my interactive design site chock full of tutorials, critiques, techniques, technologies, ramblings and a playground of experiments. Welcome to it!
