Add tile example

Looks like it's something that people like to do, having this kind of stuff:

https://fluxml.ai/

as an example would be nice (I think it can just be done with columns but we should probably write it out and check)

\begin{:columns}
\column{
**Compiled Eager Code**

Flux provides a single, intuitive way to define models, just like mathematical notation. Julia transparently compiles your code, optimising and fusing kernels for the GPU, for the best performance.
}

\column{
**Differentiable Programming**

Existing Julia libraries are differentiable and can be incorporated directly into Flux models. Cutting edge models such as Neural ODEs are first class, and Zygote enables overhead-free gradients.
}

\column{
**First-class GPU support**

GPU kernels can be written directly in Julia via CUDA.jl. Flux is uniquely hackable and any part can be tweaked, from GPU code to custom gradients and layers.
}
\end{:columns}

\begin{:columns}
\column{
**The Model Zoo**

A rich collection of Flux scripts to learn from, or tweak to your own data. Trained Flux models can be used from TextAnalysis or Metalhead.
}
\column{
**Probabilistic Programming**

The Turing.jl and Stheno libraries enables probabilistic programming, bayesian inference and Gaussian processes on top of Flux.
}
\column{
**TPUs & Colab**

Flux models can be compiled to TPUs for cloud supercomputing, and run from Google Colab notebooks.
}

Yep, it should work automatically: https://getbootstrap.com/docs/4.5/layout/grid/#auto-layout-columns
