Cell- a special plastic sheet animators use in the final stages of a developed frame to allow a static background to surround the object without much hassle.

Concept Sketcher - these might be the guys and gals making those sketch books. Concept Artists set up the basics of each scene. They crudely, but with detail, sketch a key frame of an animation in a scene. They sketch many of these, to find the right stuff. And then the animators fill in the blanks, literally. Just like the key points in a CG animation, these key frames act as the beginning and end of a certain animation of a scene, like Bart Simpson getting choked by good ol' Homer. Concept Sketchers may also actually be the ones to create some of the characters you see, but usually the producer does that.

Deadline- like any business, animators try to rush to meet a set, strict deadline, and develop Carpal Tunnel Syndrome over the years because of it.

Flip Book- sometimes the artists might make a quick flip book of the general sketches of what a single scene might take. They use a thin cardboard to draw the frames on crudely. Then they flip it through with their thumbnail to check if the animation looks right, works right, and if it speaks the scene well. They may use many of these to get the job done.

Frame- a single picture to be used in a single animation scene. A cartoon shows at about 24 frames a second. That's about 35, 000 frames for a thirty- minute episode. That's a lot of pen-scribbling.

Horizon- line in the background of the scene that serves as the focus point upon which all foreground items will be related to.

Paint - cartoon artists use special paint or inks to keep a solid color free of blotches and such.

Pen- used for the final frame process. More advanced, can't erase, but allows for bold, stunning productions. After all, cartoons would look pretty lame if they were outlined in pencil.

PENTECH Pencil- you spend all your life energy making sure you never draw with this.

Perspective Point- usually on the horizon. A point in the picture upon which objects fall into the background.

Signature- you should always sign any cool animation cells you create, they could be worth a lot of money later.

Sister Animators - I don't know if this is the technical term, but with the heavy demand for a studio to bring out new episodes every week, one studio alone, just can't do the job sometimes. So they might send the frames and tools and storyboard of a different episode to a different studio sometimes in a whole other country. There the sisters will take what the producers and artists have in outline format, and with proper training, finish the scenes themselves. Of course, then the show has to be shipped back for the right language to be applied. The Simpsons creators, for instance, commonly send an episode or two to a special animation studio in Korea. There they'll work just as hard and actually, the US may not see the actual episode for up to 9 months. That's right, some of The Simpsons episodes you see could be almost a year in the making. It's not easy making a cartoon, it really, really isn't. At least somebody does the job.
