Yeah.
He claps his hands and says "Wake up. Daddy's home" and all the holograms start up.
The cool part is that the MKI says: "Reconstruction", MKII: "Prototype", MKIII: "Battle Damaged" and MKIV says: "Awaiting upgrade".
Another nice touch is that when Pepper walks in moaning about Tony giving away his art collection, he walks past a CNC machine that has the MKVI displayed on the screen. Like the MKVI was ALREADY being fabricated prior to the trianular chest reactor. It's the first appearance of DUM-E since it handed Tony the MKI chest piece in IM1.
And also of course, the hologram of the MKV suitcase is floating in the air. Tony grabs a hologram from the air, and throws it into a basket, then walks up to the suitcase armour(It actually says "Suitcase" on the hologram), closes the case and swipes it aside.
