Runestone Hypercube is a fully on-chain interactive art piece crafted with p5js. This piece is the evolution of Lissajous Hypercube in the colour scheme of the Runestone parent inscription. Instructions: Up Arrow/Down Arrow adjust rotation speed. Space Bar sets speed to zero, f/F resets rotation speed. p/P is for point mode, l/L for line mode. z/Z, x/X, c/C toggle rotation on different axes. v/V pauses/resumes all rotation. s/S saves screenshot. Mouse Y movement changes 4D projection distance; d/D freezes it.
