Internal Hackathon: making a product from scratch within two days

The Power of Sound is a web experience about the importance of green energy and its power to change – and save – our world. We made it at our first internal Hackathon at Zajno within 2 days using such technologies as HTML, CSS, GSAP and SVG animations. The result was so good that we decided to share it with the world and won Website Of The Day on CSS Design Awards.

Our planet needs alternative energy - alternative energy needs your voice

In the experience, we imagine a future where entire cities will be powered by sustainable energy sources — sound being one of them. Accordingly, visitors to our site are asked to generate electricity with their voices — and having made some noise, they are informed of how many lights they’d managed to power. Finally, they are invited to use their digital voice to raise awareness via social media.

Every voice helps to make the change

We chose to use sound energy for several reasons. First, it is under development now and could yet turn out to be a revolutionary energy source. Second, sound and speech recognition have long been an area of our interest, so it was a nice opportunity to work with it. Finally, using voices to generate power is an analogy for raising one’s voice to generate awareness of the climate emergency. Environmental activists have changed the global agenda by speaking up – maybe we could do a little of the same.


“The internal Hackathon turned out to be an incredible experience that exceeded all our expectations and showed us what we are really capable of. We tried lots of new and fascinating things and even discovered new talents. It was an ultimate comfort zone escape that helped us unleash our creativity.”

Danil Goncharenko, Lead Front-end developer at Zajno
