Great work! Some comments: On Ubuntu 16.04 notify-send doesn't work without -u critical. Also alternative we could use this alias (need sox package to play):

alias pomodoro='sleep 25m && for NUM in `seq 3`; do notify-send -u critical "End of pomodoro"; play -q -n synth 2 pluck E3; done'

Thanks! I'll use it! :)
To make it more radical I'll flip the screen and play a sound, I post it here in case someone is looking something similar
After line 25: sleep 1500 # 25 min work
xrandr -o right
aplay /usr/share/sounds/sound-icons/xylofon.wav

and after line 47: fi
aplay /usr/share/sounds/sound-icons/piano-3.wav
xrandr -o normal
Greetings!

cool!
