Here's what they said about Got Brainy:
We are a couple of MIT guys who are trying to make SAT prep as fun and free as possible thru the power of user-generated content & peer-to-peer learning. In case you couldn't tell, we LOVE running contests and have awesome partners who are helping us make that happen.
Got Brainy has two sections- Brainy Flix and Brainy Pics. Brainy Pics is comprised of images
while Brainy Flix is comprised of short videos that illustrate the meaning of words.
This would be a fabulous site to use when working on vocabulary with your students.
