Cool Links Vol. 18: December, 2025

Hey there! It's time for the last post of 2025. I posted my yearly retrospective last week, and with this latest digest of Cool Links, I'm officially wrapping up the year.

Not many links this months as I've been quite busy, but the ones in here are extra cool.

Fun

The greatest in-camera effect of all time (video), by Corridor Crew

Ok, this video is amazing. Corridor Crew recreates the amazing practical effects from the first Lord of the Rings movie (the forced perspective ones with Gandalf and the hobbits), but not only that, there's amazing storytelling on how it was made, all the cinema history before it, and why it has never been done again since then.

Clues by Sam

Neat little daily browser puzzle game where you use clues to find out who’s a criminal and who’s innocent.

PostHog Website

This website is so cool! It's the kind of thing that you'd imagine was a personal website, but it's actually a marketing page! A marketing team actually sat down and planned this out! I thought no such thing as fun marketing existed. Glad to be proven wrong.

Size of Life, by Neal Agarwal

Another great page by Neal Agarwal; this one lets you see life in all its different sizes.

Dev / Design

The f* off contact page, by Nic Chan

Great post about how clients hire experts to solve a problem, then completely ignore their expertise and try to copy what the big ones do. But they're not big.

The "f*** off contact page" concept is amazing, too. It's 100% real and out there, with more and more companies doing it (either intentionally or by just wanting to copy what others do).

Also, Nic Chan's website is a treasure. It's already been featured as a cool link here before but I wanted to point it out again. So cool!

CSS Wrapped 2025, by The Chrome DevRel Team

CSS is my favorite language and 2025 was amazing for it! The Chrome team built this page highlighting all the new exciting stuff that happened to CSS this year. I've used some of it but sadly still have to wait for other browsers to catch up before doing it on any serious work 😭

I recommend opening this in a Chromium-based browser so you can try it out firsthand, but there are video recordings of the features in case you're unable to.

Tech

I shrunk down into an M5 chip (video), by Marques Brownlee

I usually love these videos that deal with the scale of things, and getting one from MKBHD was a surprise for sure, but a welcome one.

It's incredible how far technology has come, and it's a testament of how humans can achieve incredible things when we want to.

Wrapping up (the year)

And with that, 2025 is wrapped up for this blog! I don't know how your 2025 was, but I hope 2026 is better in every single way! Thanks for reading!
