gathering the idea together

Just finished work, had to get this written down before i completely forget everything:

The animation will be set in stone age, with two caveman collecting stone materials from a cave. The first caveman is pushing a heavy square shaped boulder, The second character is his friend is also collecting stones with him has somehow found a much bigger, lighter boulder the shape of a ball.

• the first caveman will be mature and experienced - in his 30s and unwilling to try new ideas.

• He's really tired and starting to struggle, but he need the stone material to build the rest of his house.

•  suddenly a second character appears pushing same sized bolder, but in a ball shape.

• The second character is alot younger, faster  and has found a easier way to push the stone along the path, on his knees. 

•  He stands up and shows his friend what hes done.
