Charrette - (noun) a final, intensive effort to finish a project, esp. an architectural design project, before a deadline.  

In fields of design such as architecture.... the term charrette may refer to an intense period of work by one person or a group of people prior to a deadline. The period of a charrette typically involves both focused and sustained effort. The word "charrette" may also be used as a verb, as in, for example, "I am charretting" or "I am on charrette [or: en charrette]," simply meaning I am working long nights, intensively toward a deadline.

An example of the charrette, the University of Virginia's School of Architecture unofficially calls the last week before the end of classes Charrette. At the final deadline time (assigned by the school), all students must put their pencils down" and stop working. Students then present their work to fellow-students and faculty in a critiqued presentation.   Thank you Wiki.

A daily charrette exercise. The goal is to design something daily, it may be simple and it maybe be stupid, but there it is.  A professor once told a group of architecture students that you had to drive your own work.  That is my intent.
