In this scene of my animation it needs to be clear that Lenin is in fact a button and once clicked information about him is available, below are four ideas I have had to represent that he is 'clickable'
1. Information Icon - a separate button that floats next to the model.
2. Solid Outline - A outline around Lenin breaking him away from the building showing that he is a button.
3. Blurred Outline - Blurred version of 2.
4. Solid and Blurred Outline - 2. and 3. Combined to make a more stylized outline.
