i have a python curses app that i use. it plays audio and opens browser windows with giant text that say: take a break. after years i just discovered the killer feature: locking the keyboard/mouse. now it locks input for 5 min, and even if replug usb its still locked. only reboot easily clears it. its been amazing. that little kick makes a huge difference. triggers 5sec of rage everytime, and then im up walking around. its beautiful. usually i do 40 min with 15 min break, but keyboard only locks for 5 min. after the lock, the firs keyboard/mouse input resets the timer automatically.
