NIce work. You certainly followed the specifications I submitted. Question, what are the 3 licons you used under the letters "T" "A" "L" and "G" and at the top right?
Revised with simplified colors in type. Also, changes up the icons. So you know my thinking behind the icons: Jack (toy, also reminiscent of atomic imagery and Formica patterns), rocket (toy and space race), VW Beetle, coon-skin/Daniel Boone cap, peace symbol, flower power, platform shoe. If you're not fond of any of these symbols -- or would like to see others added, please let me know.
Revised, replacing orange for purple in the type, and playing around with the sizes and positioning of the icons. Also rounded the edges of the square for the feel of a TV.
Alternate version exploring breaking up the word Nostalgiacast -- so it can be larger in the square shape (and possibly aid in pronouncing this unique word).
