Who'da thunk a glass rectangle could generate so much buzz? But the web is, and has been, undeniably a'Twitter with speculation, rumors, future stock price analyses, and rendering mock-ups of Apple's forthcoming tablet.

iLounge is tapping into the frenzy with their "Design the Apple Tablet" contest:

Submit a brand-new artistic rendition (minimum 1600 pixels wide) of what you think Apple's upcoming Tablet device should look like, including the on-screen interface. Some of the details are believed to be known here, but you're not bound to follow them. Your image may be wholly original or based in part on iLounge photos of the iPhone or iPod touch, however, originality is strongly encouraged, and no use of others' photos or previous contest entries is permitted. Please do not overlap text on top of the image of the Tablet....

For this contest, we will be selecting winners based on either the plausibility or the cool factor of their designs, and unlike some previous contests, we are not looking for funny entries. Use realistic or smart design ideas to inspire your work and you'll have the best shot at winning a prize.

Said prizes are a series of headphones way too expensive for you to ever actually pay money for. Deadline's October 26th.
