First of all, how on earth is it possible that a website inviting to a major exhibition of an internationally renowned artist does not have an English version?? I do understand French but many people from all over the world don't and I would have thought you want Lausanne to be an internationally recognised town...
Secondly, the sign posting to and especially outside from the site wans't great, I had to look for the exit and try several doors.
Lastly, I saw a similar exhibition on Klimt in Vien...
