In turbulent times, people get tired of established parties and prefer “new faces”.
But how can you know, if the new candidate is really new? We can use our knowledge of textiles and mathematics.
If a candidate wears stripes on TV, he or she will look horrible due to Moiré patterns, interference of fabric stripes and raster resolution of the camera. You can enjoy it in full motion on this youtube video.

In textile CAD system, we have to work hard to avoid Moiré patterns. Threads of various colors, weaves and designs will always form stripes, which interfere with the pixel resolution of the screen or printer. On top of that, we wish to zoom in and out of the fabric, to get overview of the whole design. In same cases Moiré patterns are unavoidable. But in other cases, they can be avoided. In the latest version of ArahWeave, CAD for textile design, we have studied many advanced mathematical approaches to solve this problem:

• Monte Carlo method
• Van der Corupt sequence
• Halton sequence
• Sobol sequence
• Supersampling

We have greatly improved over our previous results.
On the left, you see a tapestry weave colored in yarn colors, and on the right, you see just the black and white weave card (black – warp up, white – weft up). Tapestry weave is very big, 11492x4662, and we wish to make a precise and accurate fabric simulation, zoomed out 16 times.

On the left, you have our previous simulation, full of unwanted Moiré patterns, and on the right, the new one.

Now we can use ArahWeave to generate very accurate fabric simulations for use in catalogs or e-commerce web sites, based on production data (jacquard card file), not on product photos.
How can we apply our expertise in Moiré patterns on politics?
If your preferred political candidate appears perfect, speaks smoothly, just what you want to hear, and never wears stripes for TV confrontation, don't trust that person. He or she has been planted by the “old forces”, trained by spin doctors and fashion advisers. They will show their true colors, once elected.
