Did you guys see R2D2 in STAR TREK ? Well he was there.

The mystery is over. After all, R2-D2 wasn't the astromech calculating the warp trajectories for the Enterprise. Here you have the exact timing of his stellar cameo—and the frame capture to prove it. During the Drill Machine sequence as the Enterprise comes out of its barrel role amidst destruction of the other Federation ships above Vulcan, we cut to an interior Enterprise bridge over the shoulder of Kirk that is looking out through the front viewscreen. In space, R2-D2 is floating in the debris from about the top middle of the screen to the bottom right. Or is it left?

Apparently now you can find him in TRANSFORMERS: REVENGE OF THE FALLEN too. TheForce.net reports:

There's an R2-D2 flying around in there somewhere," revealed Scott Farrar, the film's visual-effects supervisor, who also worked on the "Star Wars" episodes "Return of the Jedi" and "The Phantom Menace." "There's a little bit of space junk thrown in there; see if you can find it. It's a scene in the desert." Interestingly enough, George Lucas' charismatic droid also had a blink-and-you'll-miss-it cameo in "Star Trek," which shares the same writing team as "Transformers." Is it a coincidence? "Perhaps," screenwriter Alex Kurtzman grinned mischievously. "Perhaps not."

Did any of you guys notice it? I didn't. And I'm usually so sharp. I wonder what might have been distracting me. So weird.
