Well, if you want to show the lone pair of electrons you could.

Here is a link to a pdf. I didn't think that sending you a 385 kB e-mail message
was sucha great idea:)
I thought the model was a neat idea. Unfortunately, one of the reviewers hated
it, and the other two didn't think it rose to the level of "article". I will go
back and develop an activity based on the model, but I need to find the time to
do that.
Oh yeah, after creating all of the figures, I realized that for maximum
flxibility the only bricks that should be used are 1x4's and 1x1's. So, anywhere
there is a 1x3 or 1x2 brick replace it with the correct number of 1x1's.
Eventually, I'll redo the drawings.
