I released the following sequences of images that you can use to try out Lentigram. They are also available on my website www.framedlives.com.
All images are distributed under the Creative Common Licence Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0). They can be used for testing and personal use, but they cannot be used as part of a commercial product.

Tree.zip contains a sequence of 3D images of a digital tree, good to test Lentigram 3D functionalities.

Numbers.zip contains a sequence of numbers from 1 to 128, useful to find the number of independent images that you can print on lenticular sheet. You will be surprised that it almost never corresponds to the very well known formula LPI/PPI.

Gears.zip contains a looping animation of few gears to test animations generated in Lentigram. Try the full sequence with bokeh enabled for smooth animations or only few frames with bokeh disabled for sharper movement.

Spiral.zip contains a looping animation of a black and white spiral generated with a mathematical formula.
Enjoy,
Giovanni
