4D Audio Visual Instrument

The Tesseract MRI is an attempt to visualize the 4th dimension. It explores this dimension in the same way we explore brains: by taking slices of them. By changing the position and angle of your hand, you redefine a hyperplane which takes a 3D Slice out of the 4th dimension.

If the Slice that you take intersects the 4D object, in our case a tesseract, it will reveal the part of that object that exists in the current 3D slice. Additionally, you can see the same process happening as we take 2D slices of a 3D cube, and 1D slices of a 2D square.

Inspired in part by ‘Flatland’ by Edwin Abbott Abbott, The Tesseract MRI hopes to let people understand a space that they typically cannot. By playing a note every time the 3-Dimensional Slice hits a corner, auditory feedback additionally invokes a sense of the size and the shape of the ethereal Hypercube.

Instructions:

Hold hand out with fingers spread over the Leap Motion controller. Move and rotate your hand to explore the tesseract.

Hold 1 finger up to see lower dimensional slices
Hold 2 fingers up to see an projected version of the tesseract
Hold 3 fingers up to see the 3D slice of the tesseract
