Maybe I'm just missing the joke, but it feels worth pointing out that almost all of the logos on that page are clearly inspired by the ensō circle from Zen art.
I highly recommend watching the relevant section of that video (4:38 to 8:59) and then implementing it yourself in whatever system you know that can draw lines and circles (I did it in Godot; it took only a few minutes to learn enough Godot to start on the algorithm).
It's absolutely mind-blowing that so little code can produce such a beautiful result. It's also fun to play with the parameters and see how they affect how the cloth feels.
Access has been somewhat reluctant to make BeOS-related material available in the past. For example, they did provide access to the BeOS API documentation (called the Be Book) to the Haiku project, but only under a restrictive no-derivatives license (see [1]). This has caused some pain the past, as extra care must be taken that Haiku's API documentation, the Haiku Book [2], is not a derivative work, so everything had to be rewritten from scratch, even documentation for parts of the API that are largely unchanged.
Adding the thing that complains is a one-time cost. It may work on Firefox now, but making sure that it continues working on Firefox is a continuous resource investment.
