# hacky but fun code to change the RStudio theme every (e.g.) 15 minutes,
# cycling through the themes in the {rsthemes} package.

# 
# start is 9am on the day rstudio::conf(2021L) kicks off.
# applies the current theme, then starts a timer to change it periodically.
# to rotate less often (or more), adjust theme_period below.
# (fractional minutes may not work.)
# note that breaks are just based on lubridate::round_date logic.
