Additional blocks to enhance the tags module

Ishihara Tag Cloud block

  • A bubble cloud based on the Ishihara color blindness test.
  • Original idea and JavaScript code:
  • Larger bubbles represent tags with larger weight. Smaller bubbles, smaller weight.
  • Tag names are displayed by mousing over a circle. Clicking it links through to the relevant tag page.

  • Sort order: This determines the order the tags will be drawn in. For example, "ascending" will cause the smallest tags to be drawn first resulting in the larger tags being furtherest from the center of the cloud.

  • Div width in pixels: Width of div container of the cloud.
  • Div height in pixels: Height of div container of the cloud.

  • Text font color.: Hex triplet of Color for font in Flash movie. Default; EBAF00
  • Background color. (292929)Blank for transparent, but affects performance.: Hex triplet of BackGround color for Flash movie. Default; EBAF00
    • Setting it blank will allow movie to be transparent, but at the cost of speed/performance.
  • Flash width in pixels. (500): Width in pixels of the flash movie.
  • Flash height in pixels. (500): Height in pixels of the flash movie. 3/4 of width for best results as text is wider.
  • Rotation speed percentage. (100): Speed in percentage of the rotation of the tags. Default is 100. 50 would be half speed.
  • Font size magnifier. (5): Multiplication factor of the font size so that tags with little weight will still be shown. Galleries with smaller tag weight/quantity will want a bigger number. Lager galleries with significant tag weight/quantity will want a smaller number.
  • Show title of block.: Show or hide the title of the block. Default; show(checked).


  • tags with single quotes or apostrophes stop the javascript from passing the tags to the flash object.
  • Ampersands ( & ) can only be used in tags names if there is a space before and after. Example:
    Blank & White
