[SPIRO]rat is a free plugin for Grasshopper (plugin for McNeel Rhinoceros3D) developed by rat[LAB]EDUCATION in INDIA. It generates Epitrochoids and Hypotrochoids by representing the motion of pen in a classic spirograph. An infinite number of patterns can be generated through this plugin using Rhino3D and Grasshopper3D which can be translated into spatial formations. 

rat[LAB] EDUCATION is an initiative by rat[LAB] to start a new discourse in architecture & parallel design disciplines with the use of ‘computational design’ & it’s various subsets.
Spread across various cities / countries, we are establishing a global dialogue in the domain of computational design by actively organizing and participating in workshops, lectures, presentations & symposiums.
While rat[LAB] has taken a top-down approach of exploring computational design through industry collaborations, a parallel, bottom-up approach is also in place to involve students of all levels, from design & related backgrounds.
rat[LAB]’s educational mission has led to formations of national and international workshops, programmes, discourses and collaborations which has now opened up new avenues of academic exchange. rat[LAB] has started Design Technology Tools section on their platform where new developments, tool-kits, workflows and associations will be showcased. [SPIRO]rat is now available at: www.rat-lab.org/designtechtools
