World Usability Day may have come and gone but the posters will last as a visual statement of what life might be like without it (it being usability). The examples are good but one only needs to look at almost any device today and see serious problems. I do think they work well.
The idea behind the 2006 campaign was to build an appreciation for usability by showing what life might be like without it. This was demonstated by visually removing or changing elements of everyday objects and consequently rendering them unusable.
