For an amazing animated depiction of the inner workings (molecular machinery) of eukaryotic cells I heartily recommend the following video.
Some of the items covered include P-selectin, leukocyte adherence, extracellular matrix, the lipid bilayer, lipid rafts, chemokines, proteoglycans, G-protein-coupled receptors, signaling pathways, spectrin tetramers, the cytoskeleton, actin filaments, severing proteins, microtubules, vesicles and their transport within the cell, mitochondria, centrioles, nuclear pores, ribosomes, protein translocators, the endopasmic reticulum, the Golgi apparatus, and ICAM proteins.
All this and more in a mere 8 minutes!
Highly recommended.
