You really do good job 💪 I understand more than from tutorials, courses etc. After that I'm trying write my own code. There is just a practice ! You explain everything and that's help me a lot ❤️ Merry Christmas from Poland 🎅

I’ve been watching your videos for a few months now and learn something new in each one. Just wanted to say thanks for putting this resource out there and making it as accessible as it is. Season’s greetings! Thank you! (EDIT: space-filling curves could be a fun video ;) )

This is so over my head it’s unbelievable

Render them to their own image buffers and use each one as a particle in a gravity + Brownian motion simulation. Result = realistic snowfall. Or if left as just arrays of particles, allowed them to have a speed, and made them able to break if going to fast when they hit the ground. Then let them pile up on the ground.

I'm digging that coding trail sweater, haha. I always love these coding challenges; thanks again for all your hard work.

[LoPhatKao]

Dan, whoever made you that sweater is great :D

As always, Wonderfull! I worked with DLA (for scientific research) when I was an undergrad student. Never thought it would be so much fun!!! Thank you!

[NitishKumarPatra]

I just saw your channel.. You are awesome. So much of things to learn.

[rainerwaeger]

Merry Christmas from Germany! Thank you for your tutorials and keep going!

[friendofcomputer]

Wow, can't skip these videos once started watching. Thank you so much for teaching us.❤

[jipfr]

This is the coolest thing I've seen all week (yes, I know this video is 2+ months old)

[sonik]

Merry Xmas! You made all of this look so simple ...every time I watch your video I learn something new! Thank you Dan!

[paraschavan]

To kill boredom
I do programing
I love to create things

[marcosimfeld]

I love your Videos!😱😱,
thanks to you I started my channel because you inspired me!

[Entrxpy_]

Thanks for the work you are putting into your channel, it is really great :)
Merry christmas from Germany :)

Thank you again for this interesting video and Merry Christmas from Toronto.

How about ripple animation with motion detection? Tap anywhere and a ripple motion is there BUT it can collide with an existing ripple too. Seems fun, not sure how much of it is possible though. :)

[ahmedbadal]

u are legend man ...wish i can code like u...keep it

[ryonotrio]

Idea for challenge: elastic collision of two objects: both one moving and one stationary, and both moving
