Quote - What do you guys consider art? ...

Art is that which is intentionally created to project a meaning that is more than simply the sum of its parts.

(That's my short definition, consider yourself lucky I didn't go into the full one.. ;) )

Art does not require "skill."  However, in order to make "good art", art which is successful at projecting an intended meaning greater than the sum of its parts, it takes considerable skill.

Art is NOT simply in the eye of the beholder regarding its quality.  In any medium, there are those that can understand a message and those that can not.  A lack of ability to understand a message being conveyed does not mean the creation is not Art.  Most people target everything they do to a narrow group.  It takes considerable skill to produce art that successfully conveys its message to a very, very wide audience.  But, regardless of its success, it is still ART if the intention of the creator is to make something conveying a meaning that is more than the sum of its parts.

Note: To understand the difference between Art and Illustration, look at a picture of a wire mesh and then look at a picture of that same mesh which is textured and posed in a scene, lit, etc..

The picture of the simple wire mesh in a zero pose is not intended to convey any more meaning than that which is the sum of its parts.  It's a picture of a mesh for illustrative purposes only, not an attempt to convey a message.  If there was some intent their by the artist to convey a "message" using such a pic, they would probably be a "bad" artist.

Your white dot on a black background "could" be considered Art if you are attempting to convey a message larger than just a that of a white dot on a background.  But, if that is what you were doing then that particular work probably wouldn't be considered "good" Art to a broad audience. :)

On porn - Had to mention it because it frequently is wrapped up in this type of discussion.  Many people consider "pornography" art.  However, pornography is meant to titilate and not usually meant to project anything more than the sum of its components.  In that respect, most poronography is NOT art.  There could be some that could be considered it though.  It all depends on the intent of the creator and not whether or not that creator was very successful at communicating that intent.
