FlipbookForge
Guessit the tin bird makes flipbooks by guessing each next picture from the last two. For a few frames it looks right. Then the door creeps, the ball flies through the wall, the cat behind the box vanishes. Guess the next frame yourself, flip Guessit's book and catch the drift. Predicting is not simulating.

Meet your mentor
Every Spark & Anvil app has a friendly mentor character that demonstrates, asks, and patiently scaffolds learning.

Meet the cast
FlipbookForge's animators draw small worlds that follow rules. Guessit only ever copies the last two pictures forward, so the child has to catch where its world stops making sense.
Pencilla
draws each frame by the rules of the world: the ball bounces, the door stays, the cat is still there behind the box
Guessit
A tin bird that predicts - looks only at the last two pictures and keeps going the same way, so it is right for a while and then drifts
Stayput
A tortoise who does not move unless something moves it - a door or a wall stays where it is, frame after frame
Smudger
A raccoon who keeps the hidden things in mind - a cat behind a box is still there, even when you cannot see it
Dropsy
A koala who lets things go to watch them fall - things fall down unless something holds them up
Bumper
A hedgehog in a little helmet - two solid things cannot pass through each other, so a ball stops or bounces at a wall
Evercount
A squirrel who counts the acorns - the number of things stays the same unless something adds one or takes one away
Oneway
A hen with an egg - some changes only go one way, so a cracked egg does not uncrack and the pictures have an order
Keepshape
A beaver who measures with a stick - a thing keeps its size and shape as it moves, so a ball does not stretch
Longlook
An owl who looks further back - to tell where something is going, look at more than the last two pictures
