Sushimako, my YC cofounder actually reminded me of some more details:

Here's a video [0] of Bre Pettis talking with Michi about Laser Tagging from the Graffiti Research Lab in Austria [1].

And the app by Michi and oneup (my other YC cofounder!) was written in Processing.

Hi HN and สวัสดีครับ! I remember seeing this the first time in Vienna by a friend of mine, Michi who came back from NYC and I believe he learned about it at the local hacker space at the time: NYC resistor.

I knew Michi through the Metalab, our hacker space in Vienna. Originally the idea seems to have been from the Graffiti Research Lab, which is also what I've linked to on my page and in the repo's Readme.

I think the version that Michi used was a MacOS app (not sure which framework), but I've always wanted to make it a web app. So all you need now is a projector, a laser pointer, and a laptop (with a camera).

I've already tried a few fun setups (eg using the iPhone's camera or using AirPlay connected to the projector). It's quite flexible.

Let me know if you end up using it and please share videos / photos and I'd be happy to put them up.

I know the original is old-skool cool, which I think makes this a fun project.

I'll try to set it up at the next CCC (2027) - if you see me there, come say Hi (I'll probably be in a banana costume).

Thanks! This was absolutely the inspiration - and I've also mentioned it on the page (right under the video) and in the repository's Readme.

I haven't tried, but it should be possible to do so pretty easily.

Thanks! I'm not much of a social media person (went so far that I made an Apple shortcut app to launch IG in the messages screen[0], so I can avoid the feed). But maybe I'll try to post something there.

Great writing - and happy for you that you seem to have made some friends!

I did

Just checked and it also installed itself on my phone. iPhone 17 Pro, non-US App Store, on latest iOS beta, no MDM. Sounds like an Apple Store bug to me.

My guess is nuclear tests

A fun little website I made - source code is available here:

https://github.com/consti/currentcondition

Let me know what you think?

It tried to detect which one you'd prefer. Now I made it so you can toggle by clicking on it.

Yup. I built a few more complex apps with more structure, like https://rauschstoff.com - fully vibe coded on the same platform. It has honestly been amazing the last few days :)

Also just made it open source - https://github.com/consti/currentcondition

I just made a pretty strange one myself: https://currentcondition.tv

I've added quite a few Easter eggs and a few old school games. Let me know what you think?

Blue dots are locations of previous visitors.. it all works well on desktop, the games need a bit more love to work well on mobile.

That wasn't really the intention - I hope you can find it motivating as well :)

I built a small app that includes Standard Ebooks and Gutenberg ebooks for personal library management (and send to Kindle): https://scriptwerk.com

Hopefully this makes discovery of books easier and lets people manage their libraries online - I like Calibre, but it is not great for people who are just getting started.

Congratulations! Quite the journey since we did YC S08! :D

Cool! Good chance that was mine which I posted on HN and Reddit! Great that you further improved it! Thanks for sharing!

Was an exchange student at a High School in Michigan (I’m German): Hacked the local school network to access the cafeteria system and changed my friend’s photo to Tux (Linux mascot). Would also have been able to change the credit of each student - but mentioned to the sys-admins which then challenged me to brute force their Admin password. I successfully did that and they offered me an internship. I learned a lot over the half year that I worked with them, switched from Windows to Debian (on a Mac! I wasn’t allowed to be paid, but they gifted me an iBook before I left).

While I was there I also setup a cgi (web) proxy on a host in Germany, called it “cproxy” and shared it with friends in the high school. At the end of my year, I think half the school was using it to circumvent the schools accept/reject list for web browsing. I kept it running and two years later my parents received a call from the FBI, that they wanted to have a word with me (I was back in Germany at that point). Supposedly someone used it for fraud on eBay. I remember how I had to tell my teacher in (German) school that I had to keep my cellphone with me because the FBI was about to call :-) Fun times! Really glad that the school in Michigan was so supportive and helped me keep my hacker spirit!

I've made another one that uses Facebook. But I can't tell which is worse! ;-)

..actually I think I would add a “order VR Kit” button/landing page and just see if there’s any interest.

Then start shipping a “good-enough” VR headset (possibly branded with your company) and support for your 3D files.

Any plans to support WebVR or similar? I always thought it would make lots of sense for real estate companies to allow a VR walkthrough of their properties.

Pretty sure most people would be blown away with a HTC Vive setup to walk through your future home!
