Convert from hexadecimal into binary, then convert the binary number into a bitmap.
For the second grid, ask one of your class mates for the hexadecimal values or binary from their favourite bitmap from Part 1 of this excercise. Take care not to peek at your class mates bitmap while writing down the binary.
