Wallpaper Latin?

My eldest son has bought wallpaper. It has words on it that look at first glance like Latin. However, the words don't come easily out of anything I've tried online to identify them. Are they totally made up? It's made more complicated by the fact that the font isn't that easy to read.

Can anyone translate?

Here's a bit where I'm moderately sure what it says. Tuousque (The T could be a J, and the 'n's could be 'u's) tandan nos cliam (or diam) furor.
