Welcome to the fifth day of our summer camp! Today is different than the others. It’s Laser-Cutter Day. You challenge is to spend the morning making a design that you want to last. In the afternoon we will take your designs to the Fabrication Lab and cut them out of acrylic. There are a few […]
Welcome to the fourth day of our summer camp! Laser and vinyl cutters create flat objects. Today we break out of the flat plane into the third dimension. In order to cut these objects with our tools, they must start out flat. But the objects can be folded and assembled into solid shapes. Solid objects […]
Welcome to the third day of our summer camp! All the shapes we’ve made up till now been solid objects. But some objects have holes, like buttons, donuts, and things with eyes and mouths. Additionally, our only means of adding curved edges has been to superimpose circles onto other objects. This superimposing is not a […]
Welcome to the second day of our summer camp! Today we will explore two big ideas: loops and turtle geometry. Like yesterday, we will be drawing, coding, and making. Caterpillar Code is like a caterpillar. It is on its way to being something beautiful that will bring people delight. But it’s trapped in a body […]
Welcome to summer camp! My name is Chris. Scattered throughout the room are some of my friends that you will meet soon. For the next week, all of us will be making things with technology. The tools we’ll be using to make things include computers, a vinyl cutter, a laser cutter, and a pen plotter. […]
NASA landed a rover on Mars this week. When I saw the logo for Perseverence, I felt an irresistible urge to recreate it in Twoville. And so I did: It’s not an exact match. NASA’s landings are better than my own.
Color is often represented in computers in triplets of red, green, and blue intensities. Expressing a color is a matter of finding the right mix of these intensities. For example, here are the triplets for six of the most famous colors: red = [1, 0, 0] green = [0, 1, 0] blue = [0, 0, […]
In October, a collaborator and I presented a poster on our 2D vector graphics languages at FabLearn 2020. The session started with everyone in the main Zoom room. Each presenter had 30 seconds to introduce their project, and then the crowd dispersed to individual breakout rooms. Ever since I saw someone preview their paper with […]
Yesterday I posted a checkerboard that reorganized itself by translation. This one reorganizes by rotation. And here’s the Twoville source code.
There are a lot of amazing animator-geometrician-illusionists on Twitter, and I want to be like them. But I can’t figure out how they have the time to make what they make. I comfort myself by assuming that they have no friends and no job. Despite having heaps of friends and a job, I did manage […]
