When I was a kid of 7 or so, there were less visual and aural distractions. One of the pleasures of my youth was to receive a book of paper cutouts, with cars, planes and trucks. By cutting out (carefully!) the printed images, and using the provided tabs and slots, you would gently bend the paper to shapes, and you'd come up with a 3D "model" of sorts. They were kind of crude, but they whiled away the time on evil-weather days. Far cheaper, and more creative, than a purchased toy, too.
I learned how to cut on the lines, for instance. Apparently, I was easily amused.

So, I find these "models" amusing, as they are the same thing, only x years later! Far more intricate and detailed, the Senna car above has all the detail of any model I can think of. And it's free.
There's quite a few Formula One cars, many helmets, dioramas, optional rain tires, and motorcycle stuff too! I must mention that the site is Japanese, with some English, but there are many pictures, including how to assemble these beauties. I suggest you invest in an X-Acto #1 knife, and additional #1 blades. You'll also need to use a straightedge, like a metal ruler or plastic triangle, to cut out the shapes; using
a cutting surface, like a nylon cutting mat or just a flattened cardboard box, will save your desk or kitchen table from ruin via cutting knife. See elsewere on our site for sources of art supplies. A good inkjet printer with good white inkjet paper, like Epson, will make the images all the better. There are different sizes of models to download; pick a model that suits your printer and tastes. Below is a reduced version of the two sheets needed for the McLaren above. Not all are as complex, but
all require patience and cutting skill. Good luck, and keep the bandaids (for papercuts) handy. metmania.com (scroll down)
