Clockwork Aquarium

Turn the crank to see: 

• Colorful fish swimming around the tank in a large oval! 
• A delightful crab jumping up and down. The crab looks to be lurching as it pivots to follow a passerby fish. 
• A surprise tiny sea creature (TBD) that spins whenever a fish swims by. 

Inside the fish tank you will also find amazing marine details such as: 

• Underwater green plants 
• Vibrant pink coral 
• Brick-built background including sand and rocky mounds 
• A humble clam 
• And an old helmet

Be sure to watch the videos below to see it and alternate themes in action!

(The final design will differ slightly due to part availability)

About the design:

The aquarium rests on a stately cabinet that has elaborate details all around with an ornate topper. The cabinet doors open for easy access to the internal mechanisms and the accessories stored within: fish food and chemical containers. The aquarium tank, back drop, and topper are designed to be easily separated by using tiles and reduced stud plates. This provides even better access to the internal mechanism and makes it easy to replace the background, inside features, and/or creatures. The mechanism is very robust and smooth. It involves a combination of gears, links, and a cam. My hope is to include at least 2 backgrounds and possibly 2 complete themes in the box.

From the designer:

This has been a fun project, and I am thrilled with how delightful the little aquarium has turned out. I started out working on the mechanism. I tried many different methods for creating the movement, and this version of the mechanism proved to be the most robust and smooth. I then moved on to the cabinet and glasswork. This has turned out to be a very fun, versatile, and intriguing LEGO build!
