Finally something to make visuals when sharing on video sites!&lt;p&gt;&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;watch?v=TzQt11AOslQ&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;watch?v=TzQt11AOslQ&lt;/a&gt;&lt;p&gt;This one took less than 20 minutes from scratch (never seen this app before) (rendering into 4k is another story - it is hours very slow, which is probably understandable with web rendering involved.)&lt;p&gt;Quick skim reveals it uses React and WebGL shaders to create these effects. React part is easy. Is there something recommended I could read about shaders in order to be able to contribute objects&amp;#x2F;effects to Astrofox?</text><parent_chain><item><author>mcao</author><text>Hi everybody, I&amp;#x27;m the creator of Astrofox. Surprised to see this here, but I&amp;#x27;ll be glad to answer any questions.&lt;p&gt;Astrofox has been my side project for several years now.

I&amp;#x27;ve always wondered what tool was used to make the visuals associated with pretty much every DJ set uploaded to YouTube.</text><parent_chain><item><author>mcao</author><text>Hi everybody, I&amp;#x27;m the creator of Astrofox.
