Week 35: Yarn-it-up Hyperbolic Space

This week let’s play with yarn! We are going to play with hyperbolic space. You will need some yarn and a crochet hook. You don’t need to know how to crochet, but you will need a little patience and a lot of desire to play. These don’t have to be perfect, and “mistakes” just add […]

Unbiased Trade Study (DAR)

No weights were used, the only stakeholder in the process was Kitty, and scores need not be normalized. CMMI Level 5 not achieved… INCOSE engineers may have given an eyeroll…

I love paper cutting, so last week I did kirigami with some of my classes. What was so fun about this activity is the amount of play and discovery that happened with two simple supplies (paper and scissors). Below are the videos I recorded for my classes to be able to go back and work […]

Fantasy Map Drawing Video Post from This Week’s classes

This is a post for my students on fantasy map drawing from our virtual classes this week. The video was too long for youtube, so hopefully you can all grab it here. This isn’t pro-video content (so forgive my “ums” and roughness). It is intended to allow students to pause and go at their own […]

Week 32: Isometric Drawing

Let’s get out our pencils, isometric paper, and thinking caps this week! Isometric drawings are often used in engineering and design as a way to display 3D ideas. They can also be used to create optical illusions and escheresque works of art. To start, print some isometric paper, or set your digital
