Inspiration: Hot tub [Ended]

As many of you avid puzzle solvers may know, I'm currently on vacation. As I was taking a bath in the hot tub barrel (one of these) we have here I was looking at the pipe and imagining the smoke and how it traveled upwards and gathering particles and speed. And then it hit me, what if I made a puzzle based on that concept?

I want this to be a sort of inspiration to others thinking about how they can create a puzzle. So this was my workflow:

Idea: Make a puzzle inspired by the smoke traveling through a pipe.

Concept: Make the code being assembled along the way of moving upwards, while constantly increasing in size. Binary fits this perfectly.

Visualization: Create a grid, make every X lines thicker to create separation between each set. In this case bottom is 1 row, then 2, 3... ...7, 8. Then add a bit of visual styling to it, just to make it less boring.

Define the rules: I'm calling the rows A-H. First set has A, second set BA and so on until HGFEDCBA. So set A will travel and merge with BA. BA will then travel and merge with CBA. Each time adding the values together. 0+0 = 0, 0+1 = 1, 1+1 = 10. So, for example. If A = 1 and BA = 01, when they merge they become BA=10. Once all sets are calculated, the final GA code will be the binary result at the top most set, read from top to bottom.
Note that A is always at the bottom of each set, so in the upper most set H is at the top.

Reward: Something bundled that normally is worth ~37€.

Ask me anything about creating this or any puzzle. I will freely offer advice and hints. There are no tricks to it, it's all about adding the numbers together. One thing I will not do though is post the final solution.
