Signal Lab

Every key is its own oscilloscope, and no two show the same thing: sines, square waves, ramps, narrow pulses and a struck resonance ringing itself down, each at its own cycle count and phase, all sweeping continuously across a faint dotted graticule.

The traces are drawn as continuous lines rather than sampled dots, so a steep edge stays connected instead of breaking into a dotted stripe. Nothing is drawn in the bezel gaps, so no waveform is ever cut in half.

Every other animated Stream Deck screensaver on the market is a video loop: somebody animated it once, exported it, and it plays out identically forever because there was never anything underneath. This one is a simulation that was played through and recorded frame by frame, which is why the good moments happen at different places each time it is built rather than at the same place every loop.

WHAT YOU GET. Three files, one for each deck: the MK.2 and the original 15-key at 480x272, the XL at 1024x600 and the Stream Deck + at 800x480. Use the one that matches your deck. An illustrated HTML guide and a plain README come with them, and the guide calls out the one mistake everybody makes once — the app has a "Set Image" button right next to "Set Animation", and the first one gives you a frozen frame.

HONEST LIMITS. This is an animated GIF, so it needs the Stream Deck app version 6.6 or newer. The Stream Deck MINI cannot display animations at all — that is a limitation of the hardware, not of this file, and it is better said here than discovered afterwards. Nothing here is affiliated with, licensed by or endorsed by Elgato or any game publisher; the artwork is original and drawn in code.
