+[PyStim](change) is an openly-available Python package for creating a multitude of visual stimuli in a parameterized way and is targeted towards the needs of vision science.
 It can be easily downloaded and installed via github and pip.
 Using [PyStim](change) can improve the consistency and accessibility of visual stimuli in the field, while helping to avoid bugs.
 Given its modular and application-oriented nature, [PyStim](change) supports the use and design of visual stimuli for studying visual perception.

 As stimulus creation is relevant for many vision science projects, stimulus functions which are part of [PyStim](change) or a pre-release version of the software have been used in almost all of the work of our laboratory within the last two years.

 In theory, there is an infinite number of stimuli which are or could be interesting in the future of vision research.
 Hence, [PyStim](change) will by default remain under active development.
 In future versions, we want to add more visual stimuli and more stimulus sets - particularly dynamic stimuli which are currently not included.
