Virtual Sun
We built CircadianLab, a free in-browser tool for lighting design. It uses webGPU shaders to calculate melanopic equivalent daylight illuminance (mel-EDI, formerly EML, relevant for circadian rhythm and WELL v2 compliance), photopic illuminance, UGR glare per CIE 117, and actual daylight through windows and skylights. It has a database of 400,000+ IES files from 81 lighting manufacturers and supports easy sharing of scenes/configs with other people. Daylight uses the NREL Solar Position Algorithm and a Perez clear / intermediate / overcast sky model, mixed into the same…
Virtual Sun launched on August 6, 2020 with 101 votes, #347 of 3,833 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 6 years on.
What it does
Do you wish you had a sun room? Integrate Innerscene Virtual Sun into any building to provide the ultra-realistic visual and physiological experience of being outdoors. A 3d projection of the sun follows you in the sky and changes throughout the day.
Experience the most realistic artificial skylights on the market. Innerscene's Virtual Sun creates infinite depth and natural daylight in any windowless room.
Experience Virtual Sun. UV-free, natural light replication that transforms spatial perception. Beyond beauty, our skylights replicate the spectrum and intensity of real sunlight. They support the body's circadian rhythm, sharpen focus, and lift mood. Architecture that quietly works for the people inside it, all day. Contributes to up to 12 WELL features, including L03 Circadian Lighting Design. The infinite sun. Engineered for maximum perceived depth and directional sunlight emulation in any windowless interior. Color beyond limits. A tunable sky that shifts from sunrise through midday to golden hour, supporting circadian health from dawn to dusk. The first sensor that captures the true…from innerscene.com

- BBBrowser-based light pollution simulator using real photometric dataMay 2026 · iesna.eu · ▲44
Hi HN — author here. iesna.eu is a browser-based ecosystem for working with photometric data: parsing standard luminaire files (LDT/EULUMDAT, IES LM-63, Oxytech, ATLA-S001), running design calculations against EN 13201 / ANSI/IES RP-8 / CJJ 45 / IES-IDA MLO, and (the part I most want to show off here) rendering real urban scenes in Bevy with the photometric data driving actual streetlight behavior, including sky-glow contribution. The Skyglow Analysis demo loads a real LDT file into a Bevy scene (Khronos Bistro test asset). The luminaire's intensity distribution…

Beautiful 3D ISS tracker with live video and near-realtime clouds2024 · iss.matteason.co.uk · ▲139This is a little hobby project that I hope you enjoy. You can see where the International Space Station is now, with live HD video from NASA, on a realistic 3D globe. The positions of the sun and moon are also accurate, though distances aren't to scale. The clouds are also near-realtime; I span that out into a separate project at https://clouds.matteason.co.uk, where the cloud images I create from EUMETSAT data are freely available. I've got more features almost ready to go, like the ability to turn off all UI, toggleable clouds and turning off the day/night cycle I'd love for…

Talanoa▲341Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
