I fell inlove with Ringo, and thought I'd share a few of the lovely how-to's, accompanied by my "creative" translation of the French instructions. Yes, this means I'm of the "translate the spirit rather than the literal word" school... Forgive me when I misread the spirit.
Imagine your garage as cardboard. Now cut a shape that will be a roof. Give free rein to your desires and your imagination. Imagine the shift from ground to roof to create a park on the terrace. Add a large window with a little transparent plastic. Then cut cardboard shapes and fold them to fashion columns and a gas station. As you make your cardboard garage, remember that it is possible to design and build something from 100% recycled materials.
More appropriately translated as "dead nature", Ringo's still life project focuses on broad color blocking and expressionism. To begin, choose an object that you will observe for your still life. Think fruit, plant, bouquet, cups, etc. Then select three or four colors of thick pastel crayons in flat. The colors don't need to match the color of your object; instead, focus on making sure the colors go well together. Then draw what you see!

Look around the house and studio for plastic bags, brown bags, crepe or tissue paper, and other packaging or wrapping papers that include patterns. Cut small scraps or shapes of colored paper in basic shapes. Also assemble colored stickers, scissors, and glue sticks. Now create your own outfits from the found materials. Have fun inventing matching characters.

Blow up a few balloons and use permanent marker to sketch faces on them. For a dinner party, consider drawing a portrait of each person and attaching it to their chair as a placemarker.
Have fun with your pens and blotting paper. Place a colored felt on the blotter. When it permeates the blotter, create mixed colors by asking other markers next to the first "spot". This mix will have a pretty and aged effect. Continue creating colored dots until you have a pattern you like or until the dots resemble a specific outline or evoke a feeling.
You will need one sheet of colored paper (or leftover paper bags) and one sheet of plain white paper. Starting at one end of the colored paper, fold it over to create a crease that measures about 5mm to 10mm, then fold it againso as to bring it forward. Continue doing this all the way along the length of the paper at 5mm intervals. Then cut two half circles from the folded sheet; now cut each half circle into two halves. you découperas in two. Compose a circle and then glue it on the white paper while varying the direction of the folds.
