Graphics cards can do this.

On the display board, draw the children's favorite animated characters, such as Pleasant Goat, Logger Vick and Piggy Page ... The postures of the animated characters can be starting action, sprint action, fosbury flop action and jumping action.

And the words on the display board can write the child's name, and add "Come on, come on, come on" or "You are the best" after the name. You can also add a like gesture pattern.

In short, the content on the display board should be simple, after all, it is for children to see and does not need to be meaningful. Just to convey the meaning of refueling.
