+## What does napari look like?
+

+
+## The napari tech stack
+
+:::: {.columns}
+
+::: {.column width="70%"}
+Depends on many other open-source libraries
+
+* Python based, open-source
+* Graphical user interface [uses `qtpy`](https://github.com/spyder-ide/qtpy)
+* Rendering [in `vispy`](https://github.com/vispy/vispy#vispy-interactive-scientific-visualization-in-python)
+* Images are `numpy`(-like) arrays
+* Interactive scripting with `IPython`
+::: 
+
+::: {.column width="30%"}

+:::
+::::
+
+## Who has used napari before?
+
+:::: {.columns}
+
+::: {.column width="50%"}
+* increasing in popularity
+* still a bit immature
+::: 
+
+::: {.column width="50%"}

+
+## Basic functionality
+
+On it's own, napari can:
+
+:::: {.columns}
+
+::: {.column width="40%"}
+::: {.fragment .fade-in-then-semi-out fragment-index=1}
+* open and display multi-dimensional images and overlays
+:::
+::: {.fragment .fade-in-then-semi-out fragment-index=2}
+* manipulate these
+:::
+::: {.fragment .fade-in-then-semi-out fragment-index=3}
+* install plugins

+
+
+## Why is it good?
+
+It leverages Python well:
+
+* Open source
+* Easy access to (scientific) Python (in several ways)
+* Plugin installation (and development) easy
+* (Relatively) good documentation
+* Friendly and diverse community (including designers)
+* Funding for plugins in research available
+
+## Why is it not-so-good?
+
+The immature ecosystem means:
+
+* things occasionally break (but lots of enthusiastic support available)
+* several plugins to do the same thing (please don't reinvent the wheel - re-use other people's wheels!)
+* installation trickier than e.g. Fiji/ImageJ
+
+## The possibilities are endless
