There's someone sat at a table in Ten Forward, sketching something that looks very similar to a Stargate, whilst working on a PADD with his other hand.

Orlin is working on a way to get home that Q hopefully hasn't thought of. This ship's holographic projection system is very advanced, and can program things that will likely work, if given enough information and coded correctly.

He had asked some members of the Enterprise crew on how to holoprogram, and was doing the rest, himself.
