Guar gum, a plant colloid, costs less than agar and is better suited for growing thermophilic bacteria, but is also more difficult to handle, being more viscous and less transparent. The bacterial polysaccharide xanthan is cheaper as well but forms weaker jellies that, as with carrageenan, might result in puncturing its surface. Other colloids, like alginate (from brown seaweed) and gellan gum (from a bacterium), don’t set solely based on temperature and require additives for gelation. These additives might interfere with microbial growth and make the preparation of those jellies less handy than agar plates.
But this is not the usual K-drama - this is a "micro-drama", the viral ultra-short format that has been shredding attention online. A single episode can last as little as a minute, but there can be more than 50 of them in a series. They are made vertically, for your phone and your TikTok, Instagram or YouTube feeds.

All of the examples demonstrating ordered dithering so far have been produced using a specific type of threshold matrix commonly known as a Bayer matrix. In theory however any matrix could be used and a number of alternatives are available depending on your qualitative preference. Matrices also don’t have to be square or even rectangular; polyomino-based dithering matrices have been explored as well[6].
