Are there any diagnostic sketches that report back information about the Teensy's functionality over the USB port?

I attempted the dead bug wiring depicted on the OctoWS2811 library page, rather foolish given my skill level, but I'd somehow coned myself into buying one Teensy without pins.

At present, it runs the BasicTest and Rainbow, but the PlasmaAnimation just stays white. Any thoughts as to what I've destroyed? I presume they all require the DMA connection between pons 15 and 16 work, yes?
