Simon invented this fun game in Processing after he and his little sister had some proper winter fun outdoors in the fresh December snow (quite rare for the local climate and thus immensely cherished by the little people). The game is about throwing snowballs in such a trajectory that they stick to one another, forming a super-snowball. After I finished filming this, the two snowball throwers had such a great time with the game that I dare say the giggling effect from of this 2D simulation overshadowed the real snowball fight that had originally inspired it. They did love playing in the real snow on the next day though, until it melted away.
Simon’s second Live Stream today (in two parts, see the archived versions below) was a big success! He fixed the bug in his own Speechjs library (for speech recognition and speech synthesis), demonstrated it in action and (in the second part) created some awesome looking supershapes by morphing one supershape into another.

Simon loves looking at things geometrically. Even when solving word problems, he tends to see them as a graph. And naturally, since he started doing more math related to machine learning, graphs have occupied an even larger portion of his brain! Below are his notes in Microsoft Paint today (from memory):
Slope of Line:
Steepness of Curve:
An awesome calculator Simon discovered online at desmos.com/calculator that allows you to make mobile and static graphs:
Yesterday’s notes on the chi function (something he learned through 3Blue1Brown‘s videos on Taylor polynomials):

Simon is trying to write a program for Sphere Morphing in Processing, first making a test code in p5.js (available here: https://alpha.editor.p5js.org/simontiger/sketches/S1zcwevkz)
In the video below, Simon is explaining the challenge using Magformers triangles:
Unfortunately, the test code doesn’t quite work yet: Simon is getting three infinite triangles around the circle.
Simon pulled out his old Magformers Pythagoras set and this time around, he really nailed all the tasks independently. The set offers a variety of puzzles to “prove” the Pythagorean theorem and apply it to other shapes (even 3D!), as well as teaches several more tricks (such as the ratios between the areas of similar triangles or the areas of parallelograms).

Simon built this #recursion example/ pattern (a Sierpinski triangle) in Codea (using the language Lua) while we a had a coffee at a cafe:
In the video below, Simon is showing the cloud design he contributed to the community project collecting cloud designs for the Processing Community Day coming up on October 21, 2017. You can play with Simon’s design on the community project webpage created by Coding Train at https://codingtrain.github.io/CommunityClouds/
Simon’s cloud is called “Round Cloud”. Once you open it on the Coding Train Community Clouds page, the cloud changes its shape every time you click on it.
There’s been a lot of drawing going on here lately. And jokes, like in the video above. Yesterday, after he got distracted while trying to draw the exact tangent of a circle, Simon said: “I went off on another tangent. To find a tangent!”
Oops, the Magformers are back in our life. I thought that Simon was over Magformers (which he built with excessively when he was six), but he has picked them up again and taken them to a new level. He seems to be using Magformers to illustrate his increasingly philosophical thoughts in the pauses he takes between lessons and programming. Yesterday, he was quite disturbed after building with the mirror piece for a while and said: “What if two mirrors reflect each other? Would that stop time?” He added: “Just for safety, I’m going to put the mirror in the box. Never, never ever put two mirrors opposite to each other!”
He hasn’t made it interactive yet though. This was the original plan but he got stuck.

What specially delights me about Simon’s works lately is the subtle sense of humour he writes with (probably acquired through both watching Daniel Shiffman’s videos and reading Murderous Math books):
The project isn’t finished yet as the example Simon is linking to the website is only for an ellipse and a superellipse yet:
Simon also plans to add other shapes to the website later.
