- Description: A shared screen can become a tiny stage for drawing, coding, and making each other laugh. One person moves a shape, another changes its behavior, and the experiment takes an unexpected turn.

Put two people in front of a small animation and the first request is likely to be unreasonable. Make it bounce higher. Give it an enormous hat. Can the floor disappear? A moving shape is very good at attracting suggestions, particularly from someone who has not spent the last hour persuading it to move at all.

That difference in familiarity can make a shared screen entertaining. One person knows how the scene works. The other sees what it might become. You can sit together and make something that would be less likely to occur to either person alone, beginning with an idea silly enough that nobody feels obliged to defend it for long.

## A picture with a few rules

Imagine a little landscape made of colored rectangles. A square follows the pointer across the landscape and stops when the pointer stops. There is very little to look at, but enough behavior to play with. Another person can try to lead the square somewhere awkward. The maker can change what happens when it arrives. A plain image starts to acquire the rough outline of a game.

You might discover that the interesting part is a mistake. The square slips behind a rectangle that was supposed to be the ground. Leave it there for a moment. Perhaps the scene is more enjoyable with tunnels. An accident that would have prompted a quick correction during solitary work can become a possibility when someone else is watching and asks to see it happen again.

> There is a good kind of interruption in this. A person nearby can ask for a change while the experiment is still small enough to accept it. You do not have to write down an idea for later or imagine how it would feel. Change the scene, pass over the controls, and let the next few seconds give you something to talk about.

The keyboard can move between you as well. Someone who has never touched the code may still enjoy changing a color or the size of a shape. They can see the result immediately in a simple sketch set up for that kind of play. A short comment beside the relevant number can give them a place to begin without asking them to understand the entire program.

## Give the other person the mouse

A shared screen works better when the other person occasionally gets to operate it. Suggestions from the neighboring chair can remain abstract until someone tries to carry them out. Put the mouse in their hand and the experiment acquires another pace. They may hesitate somewhere you rush through, or keep repeating a movement you thought was only a way to reach the next part.

Another possibility is to divide the controls. One person draws with the mouse while the other changes the palette with the keyboard. You have to react to choices you are not making yourself. A careful composition can become absurd in a second, then find a surprisingly good combination by accident. The program only needs a few simple actions to make this enjoyable. Save the image occasionally, especially the version neither of you is quite prepared to claim as your own.

That is especially interesting with an interactive picture. The maker knows where the surprises are hidden. A new person may spend time with the least elaborate corner or ignore the large thing in the middle. You can follow their attention without immediately explaining how to get to the supposed good part. Sometimes they have found a good part you had been treating as a minor detail.

There are wonderfully small projects suited to this arrangement. A face can follow the pointer with its eyes. A collection of shapes can scatter and slowly find their way home. A page can draw a different crooked flower after each click. The point is to have enough working behavior that another person can respond to it, then leave room for their response to change the picture.

Keep a version before making the most ridiculous suggestion. If the floor disappears and the whole little world becomes unusable, you can bring it back. Or make a second version in which the falling square is the only thing left. A shared screen gives that choice an audience of one, close enough to laugh and ask what happens if you try it again.
