If machines are good at one thing, it is making boring and repetitive things easier and/or for us, Who would have thought that this applies to art as well?
The use of computers in the arts is almost mandatory nowadays, and the tools they provide us help us make things that would have taken great amounts of time and effort to make with traditional methods.
A good example of this is pattern work, some patterns can be made with equations, like fractals, while other can be made in imaging software, like Adobe Photoshop or Adobe Illustrator.
