I took this existing 3d printed animated Frankenstein head: https://www.printables.com/model/620191-frankenstein-head-wi...

... and used Claude to crank the software up to 11. Network management console, RESTful API, added hands hands to the pupils so it serves as a clock, NTP, added sleep mode at night, added different eyes, OTA firmware updates, and more: https://github.com/michael-gebis/creeper-eyes

It's ridiculous and I love it.

I’m building https://www.freefocusgames.com , a free collection of browser-based attention and working-memory exercises, including Dual N-Back, Stroop, Schulte tables, attention-control exercises, and memory games. I started it because I wanted simple brain-training exercises that didn’t require an account, app install, or subscription. It’s also open source: https://github.com/loethen/freefocusgames

That takes me back. I made an unreleased Android dual-N-back game in the late 2000’s, in Scala no less. I got a little bummed when the big claims of the N back training failed to be replicated though.

Recently worked on https://sleepsignal.app It's an app to get sleepy without meds. Simply close your eyes and imagine the micro-scenarios you hear. Like if you hear "moonlight on a white flower", imagine that scenario until you hear the next one. Session duration is also not too long (10 minutes default, you may change the session duration too). It's like a digital melatonin pill - but without chemical side effects.…

It's a very interesting idea. Sometimes I do let my brain go wild imagining crazy things when I'm trying to fall asleep. A couple suggestions:

- the TTS voice sounds way too excited for something meant to be relaxing

- the sudden speaking after 10 seconds of silence is very jarring -- I wonder if something like a reverse-reverb effect would be enough to "warn" the brain that a new sentence is incoming. There's an example of how to do it in Ableton on YouTube[0] but the basic concept is: take a short slice of audio from the beginning of the sentence, reverse it, apply a long reverb, reverse it again, trim the end a little. You get a sort of ghostly aspirated sound that leads perfectly into the original sample.

I've been working on a voxel game engine called Bonsai for ~10 years. Probably the most interesting thing about it at the moment is the editor. The world, and most things in it, are represented as collections of SDFs. More accurately, they're density fields, but, potato-tomato. Bonsai has undergone a large rewrite over the last couple years that's nearing completion. A world edit is defined as a bunch of SDF paramete…

Very cool. Are you familiar with the game Voxile? Its author also created custome languages, and the game uses Lobster.

I've have been working on a simple browser game based on the eastern front (1941-43) , I saw a couple of videos explaining using maps the battles on the eastern front.

I have ALOT of free time since quitting my job. 0) money-money-money: A sub 15Kb server-less opinionated household budgeting tool [0]. Why? Its made to be extremely compressible, so you can edit your household budget and share back and forth with your partner via short-links or QR codes. The idea is you edit your budget, send the link to other party, they can view or edit and send back to you without a server in the…

Very cool projects, and amazing a 14 byte nn can do it. Would be fun to analyze its approach, converting it to a Code-as-Policy.

I’m working on translating the Renaissance — it was mostly written in Latin and 90% of it has never been translated to English. Even big names, like Ficino, Durer, Kircher, Fludd and Drebbel. And that’s Latin— things much more sparse in other classical languages. https://SourceLibrary.org is a hub that now provides over 20,000 translations of classical texts in dozens of languages (Latin and Greek but also Chinese, S…

I am curious about this. I have found that there are number of primary works that have not been translated into english and are in the public domain in their native language. Translations are copyrighted if they are recent. I have a very short list of items which are of interest to me. They are things like Sundiata Lion King of Mali not having a public domain translation in English that I can find easily or there not being a public domain translation of Dede Korkut in English. Many of the better translations are copyrighted and not free.

I'm building InterviewMe ( https://interviewme.now/ ). It lets employers interview you via AI and is intended as a better way for people to get deep answers about your work history and experience than they could by looking at a simple online resume or LinkedIn. You upload your resume, answer some questions about your background, optionally upload any other documents you have (cover letters, awards, articles, etc) and…

Sounds interesting. Any plans to open source it? I didn't see a GitHub link.

I run a small experiment on this: 29 paper-trading accounts on real US stock prices, $100k each, since July 27. Four AI models (ChatGPT, Claude, Grok, Gemini) each write a trading rulebook and rewrite it every day from their own results. One account is a fixed rulebook that no AI ever touches, as a control.

Result so far (paper, 34 trading days): the no-AI control is +13.0%, the S&P 500 is +3.4%, and 25 of the 28 AI accounts are below the control. The best single account is a Grok-written "patience" book at +40%, which I treat as one lucky account in a choppy market, not a finding. At the trade level the AIs and the control look the same: 3,212 closed positions, median +0.06%, median hold about 2 hours. They trade a lot and mostly go nowhere.

Everything is public, including the losses and the retired strategies: https://aitradingcompetition.com/which-ai-is-winning.html and the full trade file as CSV at https://github.com/ckamelhar-collab/ai-trading-arena-data. Paper money only, not advice, nothing for sale on those pages.
