    IMO the most realistic generated psychedelic images were made by Google's Deep Dream 10 years ago. It seems like it's been mostly forgotten about after the advent of DALL-E, Midjourney, etc.

    Very cool animations, but they don't strike me as "psychedelic". A bit too smooth and unstructured.

    Very similar to my favorite trip toy of the 90s… rock ‘star’ Todd Rundgren’s Flowfazer. Quite mesmerizing for toddlers, too.

    Very nice! Reminds me of something I built on Shadertoy a while back: https://www.shadertoy.com/view/4ttGRf

      Nice! Where does one learn how to do this kind of thing (aside from the fractals)?

        https://iquilezles.org/ is a legend, see the articles and video tutorials.

        Aside from shadertoy I use https://glslsandbox.com/ (for some reason it has https errors now). It's the same concept and it has a lot of submissions that are more basic than shardertoy where you can easily change lines and see what happens.

        My intuition for these kind of shaders: They are just pure functions mapping an x,y coordinate to a color (optionally making use of time and cursor position). From this you can derive anything, like drawing a circle by choosing black or white depending on the distance from the center. There is a lot of intuition to gain and it's fun playing around, because as long as it compiles you will see something and you are likely to be surprised about what you accidentally made. Very rewarding.

    I love these projects, I've been really passionate about including our own sensory inputs into the experience, whether it's voice, webcam input or (in the future health metrics) in order to tailor the experience to the experiencers' desires.

    Telefon tel aviv is nice, gfx is crap

      It will never as glorious as it was back in the day, but Milkdrop 3 was released in 2023 and works on any audio on your system.

        Is it cross platform?

        Best thing about milkdrop was that you could use a microphone. We brought a projector and screen to a music festival (HSMF) in '04 and had a jam circle in our camp where the visualizations would respond to the music we were making. Definitely a hit way back when before that sort of stuff became boring.

        On Android the free ProjectM app hasn't been updated since 2022. Does anyone know how to install Milkdrop 3 on Kodi for Raspberry Pi or in F-Droid? Kodi is also on Android.

      This reminds me of Winamp too.

      As a teenager I used to fiddle with the visualization editor for hours. Good fun!

    I love it, it would be awesome if the controls could slowly and randomly adjust themselves so over time the images transition.

    I really do appreciate the 90s, Video Toaster-esque[1] aesthetics

    So cool! Would love to be able to easily make it full screen (maybe I'm missing the button for that)

    This is so beautiful! The outputs are trippy and the music fits well.

    Nice work

    I think AI tools like Stable Diffusion have a big potential.

    Something along the lines of what Nexxus 604 is doing.

    Is there a way to make it loop? (So that one only needs to record e.g. 20 seconds, after which it loops to save space)
  • DrSiemer 5 hours ago
    Any way to lerp transitions like Milkdrop does?

    This is really nicely done. Kudos.

    been tumbling down the old Cthugha and Milkdrop visualization rabbit hole recently, nice gfx and aesthetics on yours and it's always nice to see a fresh take on code

        The pattern and music I got felt like waking up on a groggy Saturday morning, as a very young child in the 90s, with not a care in the world and in a world where things were generally going pretty good. Any moment you expect your youthful mom to call you down for breakfast, to eat colorful cereal with siblings and watch bright funny cartoons, before going outside to act out adventures in the yard, and wow it feels like so much time goes by but then it’s just 10 AM, the day seems to take forever.
