Of course, art is in the eye of the beholder.
To me, "modern art" is crap. Heck, the famous Picasso drew faces, to my thinking, as a demented four year old. I can draw a couple of straight lines and put a small round circle in one corner. Will I become famous too?
However I give you, in my opinion, true beautiful art as found on the net and I use as inspiration and motivation.
