Details of the animation/ movie /software

Content of the animation : Coffee is prepared from the roasted seeds (beans) of the coffee plant. Coffee contains nonvolatiles such as caffeine, trigonelline, chlorogenic acid, phenolic acids, amino acids, carbohydrates, and minerals. Important volatiles are organic acids, aldehydes, ketones, esters, amines, and mercaptans. The principal physiological effects of coffee are due to caffeine, an alkaloid that acts as a mild stimulant
Caffeine acts as a mild stimulant to the nervous system, blocking the neurotransmitter adenosine and resulting in a feeling of well-being and alertness. It increases the heart rate, blood pressure, and urination and stimulates secretion of stomach acids; excessive intake can result in restlessness, insomnia, and heart irregularities. The effects of caffeine vary from person to person, as people excrete it at different rates.
It is harmless when taken in small amount but when taken in excess it can cause nervousness, loss of sleep, headaches and digestive trouble.

All about it inside the animation.
