What about working in "B", "C", "I", into the three quadrants of the pyramid? If you do this, I suggest putting the B and C on the bottom portion with the I on top.
Do you mean #128? That's great! Unfortunately I cannot copy other designer's ideas. Honestly to me in #128 it looks like BCU not BCI but the most important thing is that you like it.
I just wanted to let you know that I am leaving out of town in two days so please take this under cinsideration if you would like to finish this project with me. I am really sorry for any inconvenience!
