Option 2:
Well you can bounce a ball against a wall for a while, take up juggling, play darts, paint or draw a picture, go for a swim. Also you may try to toss a balloon (very intertaining for me personally) or jump rope. One of my favourites, play video games (no joke, video games require both motor skills and visual perception to execute gameplay). Doing dribbling drills and building building toy (for example Lego) is helpful too. A variety of puck dribbling exercises can be also be included in your program. Boxing and many forms of martial arts are also great to help improve eye-hand coordination. In your free time, you can play baseball, golf or tennis, they will also help. You can solve spatial thinking problems or solve the same Rubik's cube. You can also practice various and interesting eye exercises. These were my options as a hand-eye coordination bracket.
