Hehe, given the age of many around here, a blast from the past is looking back on cave paintings or Heiroglyphics-like icons scribbled on papyrus.
Shoot, for some, like Doc and Jafo, who are both older than dirt, a blast from the past is revisiting the crawl marks of the first invertebrates to verture out of the oceans onto dry land.
Anyhow, for the rest of us, not so ancient members, a blast from the past would be skins from such great artists as IR Braniac; Dangeruss; Tigzz; Pixstudio and the like.
Those WERE the days.
