Organisms

Euglena gracilis

“Euglena are found in fresh and salt waters. They are often abundant in quiet inland waters where they may bloom in numbers sufficient to color the surface of ponds and ditches green (E. viridis) or red (E. sanguinea).” (wikipedia)

“Most species of Euglena have photosynthesizing chloroplasts within the body of the cell, which enable them to feed by autotrophy, like plants. However, they can also take nourishment heterotrophically, like animals.” (wikipedia)

Physarum polycephalum

Is unicellular, multinucleated plasmodium "Physarum polycephalum, literally the "many-headed slime", is a slime mold that inhabits shady, cool, moist areas, such as decaying leaves and logs. Like slime molds in general, it is sensitive to light; in particular, light can repel the slime mold and be a factor in triggering spore growth."(wikipedia)

Museum visitors could use blue, green or red light to draw patterns on the screen and observe how the Euglena reacted. The microorganisms avoided blue light, so drawing a circle around one of the microbes would trap it, which became the name for one of the scientific mini-games http://web.stanford.edu/group/riedel-kruse/publications/CHI517-lee.pdf
