Chronoshelves is an interactive display and quizz of chronological units, ideal for the study of time periods like those of Paleontology or History.

Students have to drag and drop the periods (boxes) into their appropriate places in the shelves, learning by visual reinforcement and by challenging themselves.

You can create your own chronoshelf, though if you need some help for that, do not hesitate to drop a line!


Grullo is a bilingual web app for the study of visual terminology. Add text labels to an image, and let the student change between the Spanish and English labels.

A new version is in development, stay posted for updates!
