Here's a couple of things I do when I'm not skinning for windows.
I work on a passenger ferry for a company called Color Line (http://www.colorline.com/crossings/from_germany_to_norway).
My workplace is in the buffet restaurant which is the largest restaurant on the ship (we can seat up to 650 at a time) I'm the assistant head waiter which means that I'm in charge of the reservations and seating chart. Always the perfectionist, I couldn't stand the blurry, copy of a copy of a copy seating chart we were using so I decided to do something about it!
I went into Photoshop and redrew the entire thing and here's the result:
I also did one for the A la Carte restaurant:
I've also discovered this cool online program which you can draw the floor plan of f.ex. your house. It's call room sketcher (http://www.roomsketcher.com). After drawing the floor plan, you can choose the wall and floor coverings/color etc. add furniture, then see the result in real time . I'm using the free version which only gives you smallish low-res snapshots of the room, but if you pay the annual fee you can take a 1st person 3D walk-through of what you've drawn. I was quite straight forward and I didn't have much trouble learning the proggy.
Here's the drawing I did of my house:
This drawing reflects how our house WILL look after we're done with some remodeling. The deck in the front is as we have it now but the one out back is quite smaller than pictured here.
Anyway it was fun to do!
