Play a clone of Tetris
Tetris has suggested efficacy in attenuating development or severity of trauma and it seems to have a beneficial ongoing cognitive effect also.
Don’t get Tetris™️, get a good paid version that lets you buy it and doesn’t show ads or track you after buying.
I make music with Koala Sampler, a Samson Go mic, and an $8 DAC for line-in and headphones. It’s no PC/DAW, but there’s more versatility there than you’d expect. Especially if you consider I’ve also got Csound, Caustic, and Grainstorm for creating samples and other audio processing.
Oh man, the Samson Go mic was my first ever microphone. I loved that thing!
