Oh my Goodness how did you even notice that "your music sucks" thing lol!?! I didn't even see that until I squinted and found it! It's just a rented table so who knows where that came from :-)
The "I'm Muslim When I Study" thing was just one of a bunch of big boards that showed paintings of Muslims doing regular things, like studying, helping the environment, being involved in sports, etc.
The theme of the whole week was "The Point of Origin", so the power, transcendent, and endless signs were all attributes shown of Allah. We had major verses from the Quran about Allah (SWT) set up everywhere, hanging from the second floor, on the walls, on the staircases, etc. You can even see one to the far right side of the set-up photo, but it's a little blurry.
To tell you the truth the settings weren't as good as last years, but still good alhumdulillah.
