Someone posted something & I forgot

Hi..

I'm looking for the forum thread where someone started the conversation with a triangle picture regarding the topic of Christian Education.. the picture was like a triangle-foodchain and it was in colors.

The picture strike me and I couldn't get it off my mind. I want to see it again... I've tried an hour looking for it but I couldn't remember what was the title of the thread and/or who started it.

Can someone who remember help me?

Thank you so much...
