Today, he built a Stylus Tool using the computer science concept Event.

Event allows you and all computer scientist to trigger code.

The code you wrote today told the computer to shrink the accessory when the Down Arrow key was pressed.

Today, you built a tool that allows the Stylus to envision how an outfit or room would look with different colors, accessories and accessory placements.

Take a look at these clips of a Fashion Computer Program, that combines the appearance of a person in real-time, with virtual clothing options.

We had a team, we worked on with Dezeen, was a virtual Watch Store.

So what we do, is we take one of these bespoke trackers and this is all we need.

So then, turn to the camera, get the marker in view, and boom, a watch appears.

And we've added a few bits, a little extras here, some nice texturing on the leather and to make it look more realistic, some nice reflections on the actual watch face.

Additionally, we added a bit of shadow.

Here, around the watch, just to make it feels as though its rooted more in the scene and it's more on your wrist.

So you can go through and you can select, even the colors, finishes for the individual watch.

Or you can come in and select different watches from the range.

Computer scientists often build tools to help people visualize things in new ways.

For example, 3D Printers can take an artist design to produce three dimensional tangible objects.

3D Printers can build objects made of rubber, plastic, metal or other materials.

This process is perfect for building a sample or prototype of an idea or invention.

3D Printers are also being used to build personalized devices, like Prosthetic Limbs.

A Stylus Tool can help people visualize accessories.

A 3D Printer can help people visualize physical objects.

Both of these things are programmed with code.

Remember, you can log in to the CS First and Scratch, from any computer with an internet connection.

And continue to create Scratch Projects for fun or for school assignments.

For example, you could ask your Teacher if you could create a Scratch Presentation, instead of writing a report.

Like this past CS First Class Club Member did on Dinosaurs.

Enjoy your new computer science skills.

Until next time, have fun creating and coding.
