HopSlide is a tool for authoring and playing slides. It supports animations, annotations (slide overlays), math formulas (MathML support and TeX syntax support), SVG images, and canvas graphical effects. HopSlide can be used to compile slides into XHTML files. These files can be used by XHTML capable browsers (e.g., Firefox). Compiled slide files can be used to play the slides without HopSlide.
Multitalk is a presentation program designed for giving more interactive and engaging talks. Slides are laid out in a two- dimensional canvas that you navigate in any direction, in real time, using the mouse. All of your talks can be merged into the same space. You can zoom out and create hyperlinks between slides. Each slide may also contain nested expandable sections like a folding text editor. Every slide can have an arbitrary style to control layout and visual appearance.
