You can see this banner in the site's footer:
I used the Brazilian flag for Portuguese, the US flag for English, the Spanish flag for Spanish, the Chinese flag for Chinese and the German flag for German because... I just did. At some point, this site is going to be multi-lingual and localized itself, that's just a "little further" down the roadmap for the site!
There are also text links on the bottom right side of every page:
As Google adds more languages, so will Free Language.
I chose Google because I couldn't find any totally free and cool ones that allowed browsing of the site with instantaneous translation. If anyone knows of one, please let me know. For now, this will do.
