(These battery-powered units attach to a spoke and fill the wheel with light from 16 yellow LEDs when it is spinning.) Last week, I took off the Hokey Spokes to try out something new: the Monkeylectric m132s. I’ll start with a few videos…

How many different ways can you misspell “accommodation”?

Now I, too, have generated statistics on various spellings of particular words, and have just yesterday posted them online. This includes about 100,000 spellings of about 3,000 English words, collected through the SpellBEE activity, as part of my dissertation work…
