Extensions make Piwigo easily customizable. Icing on the cake, Piwigo is free and opensource.

Key features include:

- Categories. Organize your photos in your category tree, with no limit in depth.

- Tags. Describe photos and find all of them tagged with “night + Paris + John”.

- Themes and Plugins. Change appearance and add features.

- Privacy. Make your photos private and decide who can see each of them.

Fields of painting that Krita explicitly supports are concept art, creation of comics and textures for rendering.

Modeled on existing real-world painting materials and workflows, Krita supports creative working by getting out of the way and with snappy response.

A particular focus is on the improvement of collaboration between users when assembling resources together for a project. Users can create custom ‘collections’ which include resources and saved searches, which can be shared with other users. Collections work like a shopping cart on an e-commerce site, and are always visible in a strip at the bottom of the screen.

Key features include:

- Pure web interface

- Intelligent search ordering – resources are scored against each keyword using user search activity

- Organisation, collaboration and distribution – tools to organise resources, share with colleagues on projects and distribute to others; removes the need to e-mail large files.

- Automatic resizing – resources can be downloaded in a variety of sizes so users can choose if they require high quality print files or lower quality screen / web resolution files, saving bandwidth and download time.

- Archiving – resources can be archived and are then not visible in the main search.

- User contributions – allows users to submit resources to the system, which can then be processed by a central team before being made available to other users – useful for working with remote photographers.

- Automatic thumbnail creation for most image and video file types including JPEG, GIF, PNG, PDF, TTF, Photoshop PSD, AVI, MOV, MPEG using ImageMagick and FFmpeg

It can be used to draw many different kinds of diagrams. It currently has special objects to help draw entity relationship diagrams, UML diagrams, flowcharts, network diagrams, and many other diagrams.

It is also possible to add support for new shapes by writing simple XML files, using a subset of SVG to draw the shape.

It can load and save diagrams to a custom XML format (gzipped by default, to save space), can export diagrams to a number of formats, including EPS, SVG, XFIG, WMF and PNG, and can print diagrams (including ones that span multiple pages).

The Catalog aims to connect members of the international neuroscience community to facilitate solutions for today’s intractable challenges in brain research through cooperation and crowd sourcing.

Users of the Whole Brain Catalog can:

- Fit data of any scale into the international standard atlas coordinate system for spatial brain mapping, the “Waxholm Space.”
- View brain slices, neurons and their animation, neuropil reconstructions, and molecules in appropriate locations
- View data up close and at a high resolution
- View their own data in the Whole Brain Catalog environment
- View data within a semantic environment supported by vocabularies from the Neuroscience Information Framework (NIF) at http://www.neuinfo.org.
- Contribute code and connect personal tools to the environment
- Make new connections with related research and researchers

Some usage examples include:

- operating a computer one-handed, by joystick, touchscreen, trackball, or mouse;

- operating a computer with zero hands (i.e., by head-mouse or by eyetracker);

- using a palmtop or wearable computer.

The eyetracking version of Dasher allows an experienced user to write text as fast as normal handwriting – 29 words per minute; using a mouse, experienced users can write at 39 words per minute.

For example, used in conjunction with Dasher, opengazer allows you to write with your eyes. Opengazer aims to be a low-cost software alternative to commercial hardware-based eye trackers.

TimeFlow offers five different viewing options: timeline, calendar, bar chart, table and list. There is also considerable flexibility in filtering values, combining filters, and re-arranging points on the screen.

Alembic is focused on efficiently storing the computed results of complex procedural geometric constructions. It is very specifically NOT concerned with storing the complex dependency graph of procedural tools used to create the computed results. For example, Alembic will efficiently store the animated vertex positions and animated transforms that result from an arbitrarily complex animation and simulation process which could involve enveloping, corrective shapes, volume-preserving simulations, cloth and flesh simulations, and so on. Alembic will not attempt to store a representation of the network of computations (rigs, basically) which are required to produce the final, animated vertex positions and animated transforms.
