Raven, an artist's version of a sculpted environment would come with an owner's certificate. The certificate is of course an electronic document, of high complexity (so Firewall 6+). It would be stored on either the owners commlink or on her WAN/Host as a File. The first could be physically stolen. All could be hacked. Of course, if a rich corporate exec has an expensive piece of electronic artwork in their office, it will probably require someone to enter the location due to jamming/wireless negation. The phone could be stealthily returned, with a cheap knockoff environment on it. I recommend Horizon's "My Little Bronie" Gay Furry Porn AR environment line. Or if this run is a form of retaliation/one-upmanship, perhaps a tailored "Ha-ha, I got you jerkwad" (think of what the Joker would leave behind!) environment. This might even be given to the runners by Mr. Johnson ("Place this file in Sleazy McExec's WAN before you leave!"). The same environment could be installed on a Host/Wan. Alternatively, the runners may have to find an artist that could make a replica of the environment, just like a fake painting being left by art thieves. All of this could be made harder by requiring the runners to change the ownership certificate of the artwork to their new patron's name (see page 236, Owners), either in the exec's office or at a secure site (and possibly returned). You could also make this easier by attaching the environment to specific device/artwork (like a plaque or statuette) that the runners could steal/replace if they lack hacking skills. They could sneak in, grab it and have a NPC hacker do the rest offsite, before returning it with the fake environment.
I am still writing up classic art movements and magical art. But this could also be done magically, if the runners are magic-strong but hacking-weak. An artistically-minded mage could create an Illusion and cast it through a Sustaining Focus or an Artifact. Technically, using a Focus violates the rules (it needs to be in the caster's possession). But it could be an Artifact. I personally would call it an Artifact but use the Foci rules, so that it is fragile and a Ward could disrupt it (of course there would be a Ward to get to it and to get away with it!) And a high class Artist-Wizard would be able to make such a device without needing rules, and getting a replacement would be past the runner's capabilities (but not, perhaps, a NPC's). Getting a replacement fake would be harder. One could swap in a look-alike object. Then a mage could create a new illusion and have a bound Spirit sustain it (if the mage was a Trickster Shaman, said illusion might look like Horizon's "My Little Bronie" line...).
