Pixel Pictures Keep-Going: make a new set

A fresh batch of pictures every time you click New set: some picked from a library of original pictures, some built fresh as a symmetric “space invader” style sprite. Most are decode (shade the grid to match this code); a set of 3 or more also includes one smaller encode picture (write the code for this one instead), so bigger sets practice both directions. The set number prints on the sheet. To reprint the same set later, type its number back into the Set # box.
