flash actionscript: Have a look here, there are demos of what Flex can do:

Flex is an umbrella term for a group of technologies initially released in
March of 2004 by Macromedia to support the development and deployment of
rich Internet applications based on their proprietary Macromedia Flash
platform.
Traditional application programmers found it challenging to adapt to the
animation metaphor upon which the Flash Platform was originally built. Flex
seeks to minimize this problem by providing a workflow and programming model
that is familiar to application developers.

Flex was initially released as a J2EE application or JSP tag library that
compiles MXML and ActionScript on-the-fly into Flash applications (binary
SWF files). Later versions of Flex support the creation of static files that
are compiled at authoring time and can be deployed online without the need
for a server license.

The goal of Flex is to allow Web application developers to quickly and
easily build rich Internet applications, otherwise known as RIAs. In a
multi-tiered model, Flex applications serve as the Presentation Tier.

Flex features development of graphic user interfaces using an XML based
language called MXML. Flex comes with various components and features that
make capabilities such as web services, remote objects, drag and drop,
sortable columns, charting/graphing, built in animation effects, and other
interface interactions simple. Since the client only loads once, application
workflow is significantly improved versus HTML based applications (eg. PHP,
ASP, JSP, CFMX) which require executing templates on the server with every
action. Flex's language and file structure are seeking to decouple
application logic from design.

The Flex server also acts as a gateway to allow the client to communicate
with XML Web Services and Remote Objects (such as Coldfusion CFCs, Java
Classes, and anything else that supports the Action Message Format).

Commonly mentioned as alternatives to Flex are OpenLaszlo and Ajax
technologies.
