A few weeks back, Parc de la Ciutadella in the heart of Barcelona was the site of a temporary star gate. Located in a repurposed DC 9 jet aircraft, the Portal estel-lar was a brilliant sound and light show that took passengers on a trip without ever leaving the ground. The very trippy installation was create by artist Eduardo Cajal, along with a group called PlayMid for a local festival. They hope to reprise the star gate soon. But for now, we will have to be content with the video below.
