Hello,
Below are 4 one liners which when executed produce simple star designs.
1) echo  "*" | sed  ':a  p;  s/.\{15\}//;  s/$/*/;  ba; '

2) echo  "*" | sed  ':a  s/^$/***************/;   p;  s/.$//;  ba;'

3) echo   "***************"    |  sed ':a  p;  s/\*/ /;   /^ *$/s/ /*/g;  ba;'

4) echo   "***************"    |  sed ':a  p;  /^\**$/s/./ /g;  s/^\( *\) /\1*/;  ba;' 

ThanksDave
