A mock up of what a finished level might look like.  The semi-transparent squares show which colored planes must be placed on them to make them active.  The squares of 4 colored planes are where the special bubbles float.  A special bubble is attained by filling all 4 squares with the specific colored planes.  The player can not walk on any area of the level that is not filled with an activated plane.  For a more information about our gameplay refer to Nick’s post.  This is still a work in progress, we have yet to nail down some of the ideas.

Here is a better look at the special bubbles (to be created in Papervision shortly)
