Protein Explorer, Easier to use and more powerful than RasMol. (Win and Mac only) FirstGlance in Chemscape Chime (Install Chime freeware) This is good for easiest viewing of basic structure. RasMol (Install RasMol freeware) Here's help on how to use RasMol.

Visual 3D analysis of 1FYT

STING, shows the sequence and maps the locations of sequence residues or residue ranges onto the 3D structure. Noncovalent Bond Finder displays the closest contacts to ligand or interface, reports distances, walks over water bridges.
