Task 1.5
Create your own message
Use any symbol, colour, or physical object that can exist in two different forms or states to create a poster in Binary to spell out Your Name or Greeting or Phrase.
For an extra challenge can you use a symbol, colour, or physical object that relates to your choosen word/s
For example two different states could be things like: a coin (heads and tails), a switch (on and off), colour (blue and green), shapes (circle and square)
There are to be two slides:

Chess Board Riddle
There is an old Indian legend about a King who was challenged to a game of chess by a visiting Sage. The King asked "what is the prize if you win?".
The Sage said he would simply like some grains of rice: one on the first square, 2 on the second, 4 on the third and so on, doubling on each square. The King was surprised by this humble request.
Well, the Sage won, so how many grains of rice should he receive?
