创建一个具有以下功能的互动应用程序：

### 项目概述
- 应用启动时屏幕上显示“press”字样。
- 按下回车后，一个中心位置出现一个包含点的动态图像。
- 当再次按下回车键时，当前的点平滑放大，并在中心出现一个新的点。
- 应用应无限次地继续此过程。

### UI/UX 设计与流程
- 确保加载应用时“press”消息清晰可见。
- 实现点放大时的平滑过渡以提升用户体验。

### 核心功能与逻辑
- 按下回车键后，同时放大当前显示的点并在中心引入一个新点。
- 每个新点应遵循以下颜色循环：红色、橙色、黄色、绿色、淡蓝色、蓝色和紫色，并不断重复。
- 所有点，包括新出现的点，应持续放大直到下次回车键按下。

### 最佳实践
- 确保颜色渐变平滑，具有视觉吸引力的循环效果。
- 高效处理连续回车键按下以保持性能。

Create an interactive application with the following features:

### Project Overview
- The application displays the phrase 'press' on the screen at startup.
- On pressing Enter, a dynamic picture featuring a dot appears at the center of the screen.
- When Enter is pressed, the current dot should smoothly enlarge, and another new dot should appear at the center.
- The application should continue this process infinitely.

### UI/UX Design and Flow
- Ensure the starting message 'press' is clearly visible upon loading the application.
- Implement smooth transitions for the enlargement of dots to enhance the user experience.

### Core Functionality and Logic
- Upon pressing Enter, simultaneously enlarge the currently displayed dot and introduce a new dot at the center.
- Each new dot should follow a color cycle: red, orange, yellow, green, light blue, blue, and violet, repeating continuously.
- All dots, including newly appearing ones, should be subject to enlargement until the next Enter press.

### Best Practices
- Ensure the color transition is smooth, with a visually appealing cyclic pattern.
- Handle continuous Enter key presses efficiently to maintain performance.


Q: What size should the initial dot be?
A: For example, 20 pixels in diameter.

Q: What duration do you want for the enlargement transition?
A: For example, 0.5 seconds for the enlargement.
