Along these lines, a current Kickstarter project, which uses a 3D printer and a saltwater jet in a very clever way to ablate metal electrochemically. It even presents the prospect of doing metal deposition printing by reversing the process/current (skip to 9:50).
There is also the amazing MIT synthetic biology class 'How to Grow (Almost) Anything' by David Kong and George Church. I took it during the pandemic, and it was great. It's open to anyone, but requires quite a bit of commitment.
Update: Just released v0.3.1 with Terminal.app compatibility fixed!
The tool now auto-detects your terminal and adapts gracefully. You'll see a beautiful progressive breathing animation that flows like:
Inhale: · → ○ → ●○○ → ●●●● (building up)
Exhale: ●●●● → ●○○ → ○ → · (releasing down)
Try the latest version - it should breathe beautifully on Terminal.app now.
Thanks for helping make mindfulness accessible to everyone!
I love this. Quick suggestion: make the width/height of the animation depend on your terminal size. Then you could make the animation a bit smoother for larger terminals.
Thanks for the feedback! You're right. I haven’t tested it on Terminal.app yet. It works well on iTerm2 and most Linux terminals, but I’ll review it on Terminal.app soon and update the tool or the README to reflect compatibility. Really appreciate you pointing that out.
