  I review the main observational achievements concerning GRB optical
afterglows occurred in the past two years. Their emission seems to be well
interpreted in terms of the `fireball' model, although a variety of behaviours
are observed. Evidence for supernova-like late time `bumps' in the optical
light curves is growing; however, other interpretations are possible. Fast
follow-up observations allowed the detection of faint optical afterglows, and
seem to suggest that a fraction of the so-called `dark' bursts might actually
be re-classified as `dim' GRBs. Perspectives for future observations in this
field are also outlined.
