As the QR Code read follow the white rabbit, the extract the `Wh 173 R4b B17` portion from the metadata.
At this stage, we didn't have much clue what to do, we assumed that the numbers in the metadata somehow formed a QR Code. The length of the data section is 1681 characters which is 41 x 41. Furthermore, the image was 410 x 410 pixel.
```python
import qrcode
qr = qrcode.QRCode()
qr.add_data('This is the key. Now... follow the white rabbit.')
matrix = qr.get_matrix()
print matrix
```
This resulted in a 41 x 41 boolean array, so we figured maybe the QR Code itself was the key...
```python
import qrcode
qr = qrcode.QRCode()
qr.add_data('This is the key. Now... follow the white rabbit.')
matrix = qr.get_matrix()
