Nice but a little inaccurate.
Dude? the first signs of So called movements were sort of seen in Lauscaucs cave, youre right on that.
BUT-
the first sequence drawing was an ENCHANTED DRAWING (by James Stuart Blackston) 1900 !!
And only then- the first Cell animation in 1914.
1914- Gertie the Dinasour !
1929 the Skeleton Dance!- (Disney)
Then there was a strip of horse photographs- which was a bet on whether or not the horse lifts all feets up.
The first Handrawn color Cartoon was Little Nemo .(WinsorMcCay- 1910, 1920.
1932- " Flowers and trees- the first COLOR Processed cartoon (not hand colored! (Disney)
First Cartoon With Sound was Steamboat Willie! 1928
So pretty nice flash, but youre missing the main Keypoints in animation hostory.
