Kaleidoscope Camera Fun with Shaders for live visual performances!
About this app
SpaceBeam transforms your camera feed into a psychedelic, real-time geometry pattern generator. It transmits the image as a second screen to be shared over miracast or hdmi. Features: * kaleidoscope effects * Front/Back Camera as Input source * RTSP as input-source * Image/Video (playlists) as input-source * Generative Shaders as input-source * Feedback as input-source * Different merge modes (add, subtract, multiply ...) * Accelerometer as modulation for parameters * Bluetooth MIDI controller as modulation source * BPM tap and beat synced LFOs * 9 presets slots with smooth transitions between presets * Auto-Play mode * Undo/Redo buttons
Recommended Setup: Run this app on a Samsung Android device (e.g. Samsung S20 FE). Samsung is the only system still supporting miracast. Look for the option "Smart View". Connect to any smart TV/Projector that supports miracast. Or connect to a miracast-hdmi-dongle. Optional: Use a second phone as remote camera. Take the second phone, install "IP Webcam" app. On main phone, host a wifi hotspot, or bring both phones into the same external wifi. Select the rtsp input in the app and enter the address "rtsp://192.168.30.40:8080/h264_ulaw.sdp" (the IP adress is shown on the remote cam phone when the server is running). You should get a remote image from the second phone through quite some distance. Alternatively to using IP Camera, you can use "Screen Stream" App to share another phones screen and make visuals out of any app (recommended apps: Fluid, Frakls ..)
This way you can very easily create stunning visual art setups all just with a phone and not tons of cabling and heavy computers with expensive software.
Hope you enjoy this, if you do, send me a mail :) info@calmyjane.com www.calmyjane.com
Permission Notes: Network Usage is needed for streaming Videos from other devices into the app. The app does not communicate with the internet. If your OS allows, you can block Network Usage for the app, this will cause error message when trying to add RTSP sources, but otherwise won't affect the apps performance.
Modifying System Settings is needed to force the screen timeout to infinite. The "keep screen on" flag doesnt work on all devices, if your screen turns black you can force it on in the settings menu. This needs permission to modify system settings. No other settings except screen timeout are touched by the app.

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be com.calmyjane.spacebeam is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 4.1 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall SpaceBeam first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of SpaceBeam, and a listing is removed when the evidence for it stops holding up.

Permissions Required
What each permission lets SpaceBeam do. A highlighted one is worth a second look — not necessarily wrong, just worth asking whether this app needs it.
Previous Versions
The signing certificate fingerprint for this release is on record, so a build that does not match it did not come from this publisher.
