I was recently asked to create artwork for the C.A.R.D.S. Project. Chris & John gave me no restrictions, and only one task: Create something interesting that fits on a 3.5 x 2.0 business card. For me, this was a dream project and an exciting excuse to play around with some generative algorithms!
My goal was to create an ‘ocean scene’. To do this I used Perlin noise vector fields, bezier curves, and color cycling. The ‘creatures’ or ‘waves’ are grown based on randomized parameters such as ‘width’, ‘length’ and ‘color’. The parameters change over time; some linearly, while others are mapped to cosine/sine waves and easing functions (this resulted in a more organic feeling).
I ended up submitting 250 unique cards to the project. Each card is composed of 10-frames and took 1-2 minutes to generate. Many were thrown out in the process! From there the cards were sent to GifPop for lenticular printing.
Here’s a few of my favorites (the squid in the first image is by Justin Windle):
Sketchpad v3.7 is here! Here’s a list of new features:
- High-Res export for print! 300DPI
- Autosaving to library!
- Document resizing.
- Path smoothing on Pencil tool—no more shaky lines!
- Path tool – curved path editor.
- Polyline tool – straight line editor.
- Arrow brush with curved path (or straight path)
- More background styles! Colors, gradients and patterns, oh my.
- Outline style on Shapes, Text, and various supported Brushes.
- Angle control on Linear Gradient style.
- Color Noise on Linear & Radial Gradients
- Designed for Mobile/Desktop hybrid experience.
- Improved speed of undoing multiple actions.
- Text-box resizing without scaling by holding ShiftKey.
Play around with the latest version to see for yourself 🙂
My primary focuses were creating the renderer for the Bracelet Challenge along with the binary exporter that takes peoples rendered bracelets and sends them to Shapeways for 3D printing. I have to say this job was probably the most satisfying work that’s come my way! For three reasons: (1) The initiative of inspiring a more diverse range of people interested in programming at an early age is awesome (2) Red & Co and Mash were friendly, fun and altogether great team to work with (3) The work was challenging and allowed me time to work with more cutting edge technologies 😀
The Bracelet renderer was developed with ThreeJS. My modest contribution back to the ThreeJS project can be found here: STLBinaryExporter
The letters were generated by Red & Co. and exported into STLs. Since STLs are huge uncompressed representations of 3D objects (made up of tons of triangles) the files from there were converted into CTMs using OpenCTM‘s ctmconv—this shaved 10’s of megabytes of the combined file-size of the entire alphabet. The letters were then mapped to a spiral like lego bricks as conceived by Ryan Reece of Mash. Here’s a screenshot of what that looked like:
From there, the bracelets are sent to Shapeways where they are printed with high-quality nylon plastic on 3D printers from EOS, a German printer manufacturer who provided P760 SLS 3D printers to support the initiative.
The Bracelet challenge has a limited print run, so get them while you can! After that there will still be a lot of other fun challenges on the Made with Code website.
Here’s a video from Shapeways:
