Brilliant..
I had seen some similar looking Cartoon animation, where one scene is shifted into next, using the last action of the previous scene. Forexamp, a character in animation would open his mouth, the shot of the mouth becomes larger, and the mouth is then converted into a Cave. and the Bear exits out of the cave, into a jungle, and some other creature hunts bear.. and so on and so on...
That animation was brilliant. I saw that about 10 years ago, this art is similar to that, where the previous pictures overflows continuously into next scene. There are many intelligent computer themes, animations, I have seen.
But a Continuous Theme ART, done with MS Paint, is a first. Very nicely done.
