Ideas in lowercase

This is an entry for a lowercase 'ideas' logo. Though this way was harder, the payoff was big: I now have an entirely unique entry; and, in my opinion, it doesn't look too bad.

A lightbulb represents an inspiration or idea; thus, it is fitting that a light house should be the first letter ('i') in 'ideas'. 

The waterfall 'd' can represent the flowing of ideas.

The 'e' is supposed to be a stone bridge with the underwater showing. It demonstrates how legos act as 'bridges' between our different cultures.

The 'a' is a ferris wheel with a flag pole for the tail. This shows how legos are always reusable; just as a circle is continuous.

The 's' was the hardest, yet the simplest. I tried many different ways before I got what it is now: a hot air balloon anchored (by a string in the shape of an 's') to the ground. This shows that the sky's the limit.

Thanks for viewing, and may the best builder win!
