Construction crews have started the process of preparing San Francisco's Moscone Center for the June 2 opening of Apple's annual Worldwide Developers Conference, with the first banners going up on Tuesday.

As depicted in a photo from Twitter user KielO, the banners mirror the design of Apple's other promotional materials for the event with small, colorful app icon-style rounded squares of varying sizes arranged to form the Apple logo in negative space. They also sport the conference's 2014 slogan, "Write the code. Change the world."

Earlier Tuesday, Apple quietly announced that they would be live streaming the opening keynote to Macs, iOS devices, PCs, and the Apple TV. The company promised "exciting announcements" from the address that will begin live at 10 a.m. Pacific, 1 p.m. Eastern next Monday.

Among the revelations expected during the speech are new details on Apple's next-generation operating systems, including iOS 8 and OS X 10.10. Many believe that iOS 8 will feature a focus on health and fitness tracking as well as a potential push into home automation, while OS X 10.10 is likely to get a Jony Ive-led overhaul of its user interface.
