A couple of comments/ideas.
The FWBO wheel... I don't like this because it presents dependent origination (as opposed to the transcendental variant) in a sequence not found in the suttas.
The 12 nidanas... likewise there is nothing in the suttas that says the 12th is a predecessor for the 1st. There is a sutta somewhere that says avijja (not-vijja) is the cause of avijja (not-vijja). To me that makes sense, the cause for the absence of unicorns now, is the absence of unicorns previously.
Nearly every D.O. diagram I've seen is circular and I wonder why this is so, since the Buddha never depicted it as circular and the notion of a "wheel of life" or "wheel of dependent origination" is not found in the Buddha's teaching.
"Having understood name-and-form, which is a product of prolificity,
And which is the root of all malady within and without,
He is released from bondage to the root of all maladies,
That Such-like-one is truly known as 'the one who has understood'." (Snp 3.6)
"Whether I were to preach in brief, Sāriputta, or whether I were to preach in detail, Sāriputta, or whether I were to preach both in brief or in detail, Sāriputta, rare are those who understand." (A I 333, Sāriputtasutta)
