Question: The QR code from the future was given as a gif file which showed a short video of multiple QR codes. This was their take of changing a static input to a dynamic input

Process:
1. Break the GIF into frames (each QR code) which was accomplished by using [EzGif](https://ezgif.com/split).
2. Scan 47 codes. I used the [QR Decoder](https://blog.qr4.nl/Online-QR-Code-Decoder.aspx). This produced this line of characters: }pvznalq_bg_pvgngf_zbes_qriybir_gbt_rqbp_ED{SGPX.
3. Use ROT-13 on the characters to turn it into the flag format and reverse the flag using the tool ([CyberChef](https://gchq.github.io/CyberChef/#recipe=ROT13(true,true,false,13)Reverse('Character')&input=fXB2em5hbHFfYmdfcHZnbmdmX3piZXNfcXJpeWJpcl9nYnRfcnFicF9FRHtTR1BY)). Which gives the flag **KCTF{QR_code_got_evolved_from_static_to_dynamic}.**
