You misspelled "movement" as "movment".

Typically (as per PEP-8), indentations are specified by one hard tab or four spaces, so you're good in that respect.

To be sure about formatting you can read up on PEP-8.

I am also wondering about _man. This doesn't seem to be displaying a man (but I haven't run it) so why name it that way? Also, epilepsy doesn't seem like a suitable name. Perhaps colored_box would be more formal?
