I'm posting this here for my own accountability! I plan on submitting something. I want to merge evolutionary algorithms centered around image manipulation and perhaps a poem or something nice layered on top of it. I'm enjoying learning about the Sketching library, it seems to be a rather powerful tool. I'm coming from Ruby/Python-land, so it's going to be a bumpy road but I enjoy the occasion to make something creative and intentionally non-commercial. Can't wait to see what everyone comes up with! ---

The _ **Creative Racket Competition 2022** _ starts today! Enter early - enter often. Some ideas to get you started; - Sketching - like Processing but _better_ ! Look at the repo for a brief introduction, with links to the full documentation and examples: [https://github.com/soegaard/sketching](https://github.com/soegaard/sketching) - Animate an AOC solution - use one of the functional picture libraries to create an [Escher tessellation](https://eprints.soton.ac.uk/257577/1/funcgeo2.pdf) Racket functional picture libraries ([pict](https://docs.racket-lang.org/pict/) or [2htdp/image](https://docs.racket-lang.org/teachpack/2htdpimage.html)). More inspiration from Conal Elliot [Functional Images](http://conal.net/papers/functional-images/) - Use [Graphite](https://icfp21.sigplan.org/details/scheme-2021-papers/8/Graphite-A-Library-for-Data-Visualization-Lightning-Talk-) to visualise some data Theses are just suggestions - everything is permitted! [TOOLS.md](https://github.com/standard-fish/creative-racket-2022/blob/master/TOOLS.md) has lots more tools to try.

A new entry in the Creative Racket Competition: # Miller-Rabin Liars > Primality tests like the [Fermat test](https://en.wikipedia.org/wiki/Fermat_primality_test) and the [Miller-Rabin test](https://en.wikipedia.org/wiki/Miller%E2%80%93Rabin_primality_test) rely on so-called "witnesses." In the case of Fermat, if `a^{p-1} = 1 (mod p)` , for some `a` , then `p` is probably prime. The `a` is called a Fermat witness. However, if a composite passes the test for a given `a` , then `a` is called a Fermat **liar**. The same principle holds for Miller-Rabin, although the equation is slightly more complicated. > > Which numbers are the most honest? Which ones are the most lying? That's what the given visualization is supposed to show. This is also a gradually typed program. The numeric computation happens in Typed Racket, while the visualization part happens in untyped Racket. ![1024-100000-none](https://global.discourse-cdn.com/free1/uploads/racket/original/1X/0cb5cbca0904846963d3525094a9a17814307baa.png) ---

**Tangerine** by Aeva Racket and C++ working together, Tangerine is too cool to describe here so please check out the entry issue and the Tangerine repo > > > \## Description > My entry for the Creative Racket Competition is a library I've b…een working on for creating art out of implicit surfaces, called Tangerine. > > The primary feature of Tangerine is its renderer, which is incomplete, and is not ready to be incorporated into other projects or otherwise be judged. However, the language for describing models by combining signed distance functions is quite powerful, and is likely to be attractive for other creative uses. > > For this competition, I've reworked Tangerine to be functional as a stand alone library without the renderer, and added an export function so that models may be saved out as voxel models in the MagicaVoxel file format. Additionally, I have also written documentation for this mode, which with the examples already in the repository should hopefully be suitable for people to actually use this to create novel 3D art. This mode is called Tangerine "\*Miniscule\*", and it is available for AMD64 systems running Windows or GNU/Linux. > > Beyond the scope of this competition, I am planning on expanding this mode further with other 3D model formats for export, support for color models, adding new functionality for robust model creation, and methods for spacial queries which may be useful for things like physical simulations. > > \## Location for Entry > My entry link and the code link are the same. The library and the documentation are found on \[the project's github page\](https://github.com/aeva/tangerine). I will also add a few more example images as replies to this thread after I finish writing this post. > > \## How you made your entry? > Both variants of Tangerine only uses Racket's standard library, and a C++ backend. The #lang is racket/base. > Tangerine "\*Miniscule\*" use the C++ library \[MagicaWriter\](https://github.com/aiekick/MagicaVoxel\_File\_Writer) for exporting MagicaVoxel files.
