This is a list of themes made by members of the TiddlyWiki Community. Themes change the look and feel of TiddlyWiki, allowing for another degree of customisation. Installing themes works the same as plugins.
Moments is a beautiful free and responsive theme available for wordpress from here: http://www.s5themes.com/theme/moments/. This is an adaptation of the same for TW5 platform. All the design credits goes to the site and the original designer. If TW5 is going to be here for 25 years, might as well suit up.
