[Design-team] high-school interns 2017

[Maria Leonova]

Everybody,

please join me in welcoming our long-term high-school interns Martin 
@modry and Tereza @terezahl! Here's a blog post I wrote to sum up their 
first month:

In short, they are grammar school students, very talented and interested 
in design. Tereza and Martin have been on the team for a month, and 
already have done*a lot *of much needed work. We're lucky to have them!
