Abstract We demonstrate a time-lapse video approach that allows rapid examination of the spatio-temporal dynamics of Dictyostelium cell populations. Quantitative information was gathered by sampling life histories of more than 2 000 mutant clones from a large mutagenesis collection. Approximately 4 of the clonal lines showed a mutant phenotype at one stage. Many of these could be ordered by clustering into functional groups. The dataset allows one to search and retrieve movies on a gene-by-gene and phenotype-by-phenotype basis. Background Spatially and temporally evolving collective dynamics act critically to coordinate multicellular development. In general periodic phenomena are prevalent in transcriptional regulation - for example in circadian rhythms 1 Msn transcription factor regulation in yeast 2 and the pulsatile response of NF-kB and p53 in tissue culture cells following stimulation 3 4 . Oscillations seem to be a universal
