Cool Things for Cool People: March 2026

Cool Things for Cool People: March 2026

Hey there folks! It’s time for another Cool Things, and my my, have I a round up for you! Fun “games”, a returning fan favorite, and some educational materials… Plus the introduction of a new passion project of mine. Let’s go!

What’s my JND?

Your JND 0.0029
Okay this is genuinely impressive. You're well below the standard JND of 0.02. The CIE should be sending you a job offer. Or at least a certificate.

JND, or Just Noticeable Difference, is a way to measure how well your eyes can tell apart two barely perceptible colors. This game is a fun way to test your eyes (and your screen) by identifying where one color starts and the other begins. How low can you score?

Fish Doorbell is back!

That’s right. As noted in the April 2025 cool things, The Fish Doorbell web cam system is back on for spawning season. Tune in and see if you can spot a fish (and ring the doorbell to let them through).

Channel Surfer – Watch YouTube like it’s TV

So this is super fun. You can use Channel Surfer to tune into YouTube like the days of ye olde TV guide station (or the TV guide on your cable box). This is super cool and a unique way to find new YouTube videos and channels to follow! 

How do LLMs work? A visualization guide

This chart shows a really neat visualization of how LLMs work. Zoom in and out of this slightly 3D chart and get information about each step. Tip: don’t view on mobile, because most of it is cut off. Make sure to open this bad boy on desktop!

Block LLM/AI on the web with this easy uBlock filter

Bluesky screenshot from Stevoisiak: I made a filterlist for uBlock Origin to remove Generative AI features on websites. Includes blocks for
* Google AI Summaries
* YouTube Ask button & chat summaries
* GitHub Copilot
* Facebook AI chat
* X's Grok buttons
* Deviantart DreamUp
* Booru AI images
* And more

Steve’s GenAI Blocklist is a nice and easy set of filters you can add to uBlock Origin to start culling AI search results and more from your daily web browsing. Gone are AI overviews on Google and a whole lot more. Definitely give it a go if you’re sick of turning up useless AI slop.

Need a Human Artist who won't use AI? Here's where you can find one... 100% Human Made, No AI Used

Recently, I’ve taken on a small passion project – HireHumanArtists.com. The problem: many authors and various other people looking to have art made simply do not know where to find pockets of artists. Even more, they don’t know where to find artists who won’t charge them money just to have AI make something. I’m aiming to solve that by creating a directory/spreadsheet of artists who vow that they don’t (and will never) knowingly use AI or LLMs in the creation of their works. The first iteration is a simple spreadsheet, but if all goes well and it becomes a useful resource, I’d love to build it out further. Check it out now!
