Why Write another Slideshow System?

WYSIWYG Slideshow applications are annoying
- too much fiddling, not straight to point

LaTeX is not exactly casual

Existing browser slideshows are
- based on JavaScript
- Either verbous HTML, or unflexible markup

Why avoid JavaScript

Nothing wrong with JS as a programming language, but...

Freedom to Use, Study, Share, and Improve can in practice not be applied to code served from another computer (regardless of the license this code is under)

Impossible to get browser security straight for Turing complete programs
- → Massive security problems, which are fundamentally unresolvable
- HTML and CSS are not Turing complete (CSS is a regular language)

Performance killer in practice

Simplifying HTML

Maintain the flexibility of plain HTML. Decrease verbosity of the code.

  <html>
    <head>
      <title>Demo</title>
    </head>
    <body id="frontpage">
      <h1 class="top">Headline</h1>
    </body>
  </html>

  [html
    [head
      [title Demo]
    ]
    [body #frontpage
      [h1 .top Headline]
    ]
  ]
