I quite like Wikipedia's entry..
Thus one could observe that:
Due to ignorance (of underlying realities of existence) we process/ferment what comes to our mind.
This processing/fermentation causes karma to form and mould the status consciousness (vinyana).
The functioning/existence of the status consciousness has a close association with regards to sustaining life (one's existence).
"Name" and "Form" describes the non-material and material components of one's existence. "Name" are the constituents one's mind, consciousness and ideas... "Form" (material) are the constituents of the body (made of solids, liquids, gasses...).
The six sense bases of perception are composed of "Name" (the mind/vinyana...components) and "Form" (the solids, liquids, gasses... components).
6, 7. When the six sense bases of perception comes in contact with entities (ex. eye with external world, nose with fragrances,... mind with thoughts/memories...), they generate feelings (in the mind).
Next we generate/get desires for these feelings.
These desires makes one "cling onto" them (wanting more...).
10, 11. This clinging causes the generation of causations/factors (karma) that causes/leads/drags one into future births, so that such accumulated karma can take effect, can materialise... (The generation of sankhara /karma due to attachments, desires, longings, cravings... or due to the aversions, angers, hates... generated during the cause of such quests/pursuits... will lead one through eternal samsara resulting in the generation of yet further causations/karma, requiring further... Thus bonding one into this eternal journey...)
Then once one gets into a birth, one undergoes/endures all the sufferings associated with such...
But again due to our ignorance, we fail to realise the underlying nature/reality of existence. Thus veiled and shadowed by ignorance, we keep on generating the mental fermentations/volitions that keeps one further bonded to samsara...
Thus the cycle ever so continues for ever and ever unto perpetuity... Thus breaking away from this cycle (by "eradicating"/overcoming ignorance), leads to its cessation (cessation of the perpetual wandering)....

And also I saw this anology of the twelve nidanas represented in the social setting of a part...
Ignorance enter the door, don’t know anyone, no reference point, freeze, go numb, heightened self consciousness
Formations can’t stay at the door all night, must do something, impulse to find a landing spot, vision narrows to find a reference point, head for the bar
Consciousness have now made it into the party, but need to nourish yourself, oral compulsion, have a drink
Name/Form feel warmth pervading body, feel fortified, empowered, embodied, feel more expansive
Six Senses survey the situation, look for someone to talk to
Contact See someone interesting who catches your eye.
Feeling person looks good, attractive, worthy of our attention, we feel good
Craving desire to talk to them, engage them, irresistible impulse, so lonely
Grasping mind is fixated on how to approach them, Can’t ignore them, already
Becoming go over to talk to the person, yak, yak, yak
Birth Get to know the person, give birth to a relationship
Aging & Death conversation, focus starts to flag, diffuse, interrupted, reference point dies, gap no one to talk to
Ignorance panic, go numb again, heightened self consciousness, aloneness
Formation head back to the bar for another drink ...etc!
