Actor-turned-rapper Drake released a new virtual reality tour of his upcoming 21,000 square foot mansion in Toronto today, and one aspect of the house stands out above anything else: the oversized paintings of id Software founder and Doom co-creator John Carmack.

Carmack, who is now the CTO of Oculus, and Drake have never worked together. Drake has never worked on a virtual reality game. As far as I know, Drake hasn’t even played Doom. So why, then, does Carmack adorn Drake's walls?

Here’s Carmack in the recreation room.

And once more in the recreation room, just off to the right.

It’s not just Carmack, either. In Drake’s master bedroom, there’s a picture of Valve CEO Gabe Newell hanging on the back wall. The machine beside it? That’s an arcade cabinet version of the Android game Tappy Chicken. Drake isn’t involved with the creation of Tappy Chicken, and as far as I can find, has never even mentioned it.

So again, why is it there?

The VR tour was created by the VR and graphic design firm Opiats. According to the company’s website, its mission is to create “the experience of being inside pioneering architecture, design and interior projects, to thrill-seeking surreal experiential marketing videos to hanging out with your favorite music artist at a VR Block Party.”

“We're working on getting it released to Steam, Oculus Home, and Viveport as well,” an Opiats representative told Polygon, “with an interactive version coming when we launch on those platforms.”

Neither Carmack nor Newell are investors in the firm, so the inclusion of their portraits seems to be an advertising tactic for the company. It’s very unlikely that Drake’s actual mansion will have oversized portraits of the two tech pioneers — especially in the master bedroom. Whether or not he includes an arcade cabinet of Tappy Chicken is also yet to be seen.
