is there a way to pop out window from a frame?

[biotech]

i was doing some 3d things with unity3d, and i want to embed them into web pages, or to allow others to embed it into their pages...so i managed to do it with frames. now, there is a problem when i want to open the link to my site
from the application that is embedded, it opens the window but in frame, so that is just bad... embedded window is small, a bit larger then youtube default size, so it looks ugly when it opens site in it....

is there a way to pop up the window, or to open new tab from the frame?
and not to involve making scripts outside the frame because it will be harder to present the user what he needs to do in order to embed this content into his page?

any ideas? thank you!
