Sierpinski weave rings by markdow Sierpinski weave rings by markdow
The ribbon is a single topological loop, a Sierpinski curve with a crossing.

After debugging, any computer program useful in more than exactly one way will not meet its design criteria, and neither the author nor the machine will be aware of the failure. For example, learning to ride a bike, or teaching how to ride a bike, requires a failure to know how to ride a bike. The design criteria should be revised to reflect the machine's behavior, making it counterproductive to test for, or otherwise find, errors.

"...many things only become apparent once a certain amount of work has been done on a new system, allowing a user to experience it. This experience will yield insights, which will change a user's needs or the perception of the user's needs. The system should, therefore, be changed to fulfill the changed requirements of the user. This can only occur up to a certain point, otherwise the system may never be completed." From "The Mythical Man Month":

"Some textbooks make it sound as if software engineering is a formal process of making out lists of specifications, milestones, and the like, [but] the process is also an experiential hands-on endeavor. You donít ride a bicycle by making out lists of part numbers. You have to get on it and lurch around." From Three Questions about Cyberculture, an interview with Rudy Rucker.

"[C. S. Lewis] believed human beings are wired to perceive inference (if ... then) and other mental logical phenomena as representing truths about the external world that can be learned from, rather than representing purely internal phenomena to be characterized as error. ...People continue to have faith in the phenomenon of logic, despite the fact that they sometimes make demonstrably mistaken inferences."

The three I linked to in the comments, and an image editor for the linear gradients.
