Carl Sagan had a multi part TV show on PBS 20+ years ago called "Cosmos' in which he described a tesseract.
Picture a smaller clear plastic cube within a clear plastic cube. Then connect the corners of the smaller cube directly across to the corners of the larger cube.
OR you can look at a picture of one using the link..
HEY a 2D representation of a 3D object which represents a 4D object... Melt MY Mind... Oh Wow.... :-)

I don't know but it's *made of* cubes plus the stuff inside it.
Like a cube is made of 6 squares plus the stuff inside it.
Supposedly it's only possible to show the shadow of a hypercube and impossible to see one in real life.
Like a circular disc that's slowly spinning, passes edge-on and then comes up as a triangle, then passes edge-on again and comes up as a circle of the same size.
Such an object would be impossible in real-life, but is the shadow of some weird 4-dimensional circle-triangle.

To illustrate, start with a square. Move a copy of the square to another place in 3D, and draw the paths traced by the corners of the copy. That makes a cube. You can repeat, moving a copy of the cube to another place, and draw the paths traced by the vertices of the cube. Viola! You have a picture of a tesseract, either as a model in 3D space, or as a drawing in 2D space.
Look at the wiki article to help you visualize. It should be added that there's more than one way to pictorially represent a tesseract, just like there's more than one way to pictorially represent a cube.

Think of 2 lucite cubes, one inside the other with all the corners connected. It is a 3-d projection of a 4 dimensional object.

You can find Web sites that product the 3-D "shadow" of a tesseract. I think the following Web site has the best one I've seen. If you have the 3-D glasses, I'll bet it looks really cool.

is a hypercube a four-dimensional object? (sorry for answering your question with a question?)
