Created by industrial design student Joonas Saaranen, the Reppo II backpack features a built in pair of full-range speakers and an amplifier, so you can kick out the jams as you walk down the street. The only thing better would be if that big black patch were a subwoofer. Of course, that might shatter your vertebrae if you turned up the volume too much.

Saaranen’s concept design has gotten as far as a functional prototype at this point, but he hasn’t revealed if he’ll ever have them produced en masse. In the mean time, if you happen to be in Berlin, Germany (where Joonas currently resides) and hear someone coming down the street wearing this bad boy, offer up the mad props he deserves.

At first glance, it’s hard to get over the ridiculously suggestive shape of the Torre Agbar (Agbar Tower), but it’s the cool light show that’s really the eye-catcher here.

The 474-foot tall, 38-story office tower has over 4,500 LED devices that can be computer synchronized to display massive, colorful images wrapping the entire building. The building was designed by noted French architect Jean Nouvel, whose designs include the Guthrie Theater in Minneapolis and Tokyo’s Dentsu Tower among others.
