Timer Mk3

# Filename:
# Version.: 19042017
# Author..: robz
# What another one!
# Improved from the "Egg Timer" script, a countdown timer with progress bar.
# This one has an indication of time remaining provided by Zenity's progress
# bar function. You'll need to choose a sound file below and maybe fiddle with
# the vector_tl function x&y coordinates.
