For this task I created a room using 2 point perspective, finding the vanishing point off in the distance and then using the shift key and the directional lines on Photoshop to draw out where the edges of the room would be.

I then drew in perspective a sci-fi themed room complete with a desk and chair, door, monitor and controls and even a humanoid figure being grown in a tube-of-some-sort. When drawing this I had to keep in mind the perspective points and make sure that it all lined up correctly.
