I have to make something that looks edible, but is not. It can be a representation of something real or innovative.

I also have to make a package for it-something that displays and protects.

We can use any materials for it. It also has to include either a tetrahedron, octahedron, icosahedron, dodecahedron, tetrahelix or a deltahedron.

have to use one lap joint and one doweled joint out of wood

we can use any materials except food.

any ideas?

Sure! Let's start by brainstorming some creative ideas for your project. Here are a few suggestions that incorporate the required geometric shapes and joints:

1. Edible Fruit Display: Create a fruit-shaped sculpture using wireframe structures made out of wooden dowels and joints. Attach colorful fabric or paper to represent the fruits and use a geometric shape (like an icosahedron) as the centerpiece.

2. Plant-inspired Art Piece: Design a representation of a plant using a combination of wooden dowels and geometric shapes. The joints could be used to connect branches to the main stem, with each part creatively painted to resemble leaves, flowers, or even a fruit-bearing tree.

3. Illusionary Dessert Packaging: Construct an illusionary dessert package using cardboard or strong paper material. Incorporate a tetrahedron as the main structure and decorate it to look like a multi-tiered cake or a cupcake. The lap joint could be used to secure the base, while the dowel joint connects the decorative elements like candles or frosting.

Remember, the goal of this project is to create a visually appealing representation of something edible while ensuring it is not actually food. These suggestions offer a starting point, but feel free to adjust or modify them according to your preferences and available materials. You can also consider adding other embellishments or details to enhance their overall appearance.
