RectangleWorld is a blog by Dan Gries. I initially started this blog to share some tutorials and code in HTML5 canvas and JavaScript, but the blog later branched out to include some little artistic experiments and web applications. The blog has been largely neglected for some time now, but visitors still find some value in it!
My creative energy these days is devoted to generative art. Stop by my webpage to see some of my work.
As for the name of the blog, RectangleWorld? The domain name was just as ridiculous as it was available.

Hello,
Grats for your work and thanks for sharing it.
I’d like to know how your works are licenced. I think that there is some blur in the rights of the tutorials all over the internet.
For an example, I have seen many codepen works used even in commercial purpose.
Tutorials are supposed to help to learn, and many people are able to do the same, just by fastly learning how the others did.
So can you tell me what are the licences of your presented work ?
Sorry for my quite bad english.
Best regards.

Hi Blib,
Sorry for never responding to this. I guess I have never really made licensing clear…I suppose I prefer to have people contact me about using specific pieces of code. But generally I am aware that putting my code up here for all the world to see will result in people using it, and I hope people find it helpful. I just hope that people will be respectful, so that if they post large parts of my code to places like CodePen that they give me some credit and perhaps a link to my blog.

Hi Dan Gries,
I love Nova – HTML5 Canvas Particles.
Can you make a demo like water fountain you had in flashandmath.
Thank you

Hi Satya! I’m glad you remember the fountain at flashandmath. I’m afraid I do not have time to put together a new JavaScript version of it.

Hi, Dan. Thanks for your paper snowflake maker. We’ve enjoyed it for years. We really enjoy cutting out the designs we make with it, and you can check out some of our creations here: http://www.alexwarstadt.com/snowflakes.
We have a few suggestions for taking your snowflake maker to the next level. First would be for an image of the original bounding triangle to remain, even when sections are cut away from it. Second, it would be ideal to have all the polygons to remain, so that any of them could be tweaked as the design evolves. Finally, we would love to be able to draw curves, such as Bézier curves, in our snowflake designs.
Thanks for enabling many fun evenings by the fire!
Best regards,
Alex and Denise
