This is a fairly elementary-level video on Epicurean physics, submitted to the Facebook group. Some might find it useful, at least as an inspiration to do something similar while speaking a little more quickly. 
And hey - at least the first ten minutes doesn't focus on mangling Epicurean ethics - he waits til around the 11:00 minute mark to start repeating the conventional views of that, and then he skips through that pretty quickly to other basic issues (death, etc).
Update: Actually a good reminder that Epicurus discussed conceptually the "parts of the atom" (around the 10 minute mark.)
