If you see Pi floating by on the screen at the start, turbo mode isn't on, so enable it.
If we take a line and spin it around, and then put a second line on the end of that line and spin it around but ~3.14 times faster, we get this visualization of the irrationality of Pi. It looks like it connects back with itself, but never really does. This makes me wish Pen could be more precise, but alas, this is a fine-point as it gets to my knowledge. Happy Pi day!
