Subway Animation Assignment

While in London travelling on the Tube I noticed the animations playing in small A3 sized screens as you went up the very long escalators. It was nice to see something artistic and often based around a nature theme in the clinical, mechanical and often stresssful environment of subway stations.
Create a similar 30 second animation trying to reach the rushing audience seeking relief.
Keep within the theme of nature.
If stuck for ideas choose from the following;

• Butterfly landing on a leaf
• Leaf falling from a tree
• Waterfall
• Bird feeding chicks
• Thunderstorm
• Sunrise/Sunset

Remember the screen is long and thin. Take note also that the station is devoid of natural light. Keep your colours bright and cheery.
