And then you dig in and discover it somehow also has keyboard &amp;amp; mouse input handling, can play sounds (and can be used for live procedural music), simulate a piano keyboard, and probably a bunch of other stuff I&amp;#x27;m forgetting. It was my go-to tool for visualizing any kind of math back during the university years.&lt;p&gt;In fact, I just took a look at it again (after not using it for years) and I discovered it has networking capability, IDE features, and - I kid you not - it seems to compile the scripts down to native code, offering a helpful x86 ASM output in the built-in debugger. It can dump executables, has bindings to OpenGL and support for old-school VR (colored stereoscopic, NVidia 3DVision).&lt;p&gt;&lt;i&gt;All in an executable that weighs 746 KB.&lt;/i&gt;&lt;p&gt;It&amp;#x27;s hands-down one of the most impressive pieces of software I have ever seen.&lt;p&gt;&lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;advsys.net&amp;#x2F;ken&amp;#x2F;download.htm#evaldraw&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;advsys.net&amp;#x2F;ken&amp;#x2F;download.htm#evaldraw&lt;/a&gt;&lt;p&gt;EDIT: And if you give it a try, be sure to check some of the ridiculous amount of examples it comes bundled with, which include games, explorable explanations, infinite calendars, optical systems simulations, and a whole host of other stuff.</text></comment>

I might make this my bookmarked default version.&lt;p&gt;If interested, here are a few thoughts:&lt;p&gt;- It might be good to link directly to IQ&amp;#x27;s version of GraphToy, rather than his homepage.&lt;p&gt;- I dig the white background option!&lt;p&gt;- The create link feature is a bit smoother than the original.&lt;p&gt;- The download image button is a great idea, though I just realized with both versions you can right click to save the image, without needing a new tab. One thing that occurred to me -- it would be &lt;i&gt;killer&lt;/i&gt; if the download image version popped up an SVG render with a higher sampling rate, instead of pixels! A little text or UI could clarify how to save a pixel version vs a vector rendering.&lt;p&gt;- I like the escalator function used to demo the time variable! I&amp;#x27;ve used that very function on ShaderToy.&lt;p&gt;- It would be super nice if the plot window used a flexbox or grid layout to stretch to fill the window. It&amp;#x27;s currently a bit smaller than IQ&amp;#x27;s and doesn&amp;#x27;t resize.&lt;p&gt;- Might also be nice to have the help box be a popup you can click (the way it works in ShaderToy), and maybe put the variables underneath the plot, to allow the plot to expand to basically full screen?</text></comment>
