Cover image for Submission for #levelupwithbubble
App Name:

Submission for #levelupwithbubble App Name: STUDYO Category: Education & Learning Live Link: https://gabrielcastrodias.bubbleapps.io/version-test The STUDYO prototype starts with a simple idea: what if learning worked more like thinking? Instead of linear formats, STUDYO organizes knowledge through connections. From a single topic, AI generates a structured mind map, revealing key concepts and their relationships. Each node opens layered content — from summaries to deeper explanations, supported by images, videos, and curated references. STUDYO also introduces a collaborative layer. Existing maps can be reused, expanded, and reorganized, allowing knowledge to grow over time through contributions. Flexibility is central. Users can reshape structures, move ideas, and define their own way of learning.

Cover image for A personal art direction study

A personal art direction study inspired by Aperol. Concept: “Fresh dip like a…🔥” This project explores the refreshing sensation of summer — that instant feeling when you dive into a pool or take the first cold sip of a drink under the sun. The idea was to translate that moment visually through a mix of photography and bold graphic shapes. By blending cut-out photography with fluid and geometric forms, the compositions create a sense of movement and immersion, as if the images themselves were dipping into color and freshness. The goal was to create a playful and contemporary aesthetic that captures the light, social, and refreshing spirit associated with Aperol. This is a personal creative exploration of how graphic forms and photography can merge to express the feeling of a refreshing summer “dip”.

Cover image for A personal rebranding study inspired

A personal rebranding study inspired by the Museu de Arte Contemporânea de Sorocaba (MACS). This project explores a conceptual rebranding for MACS, rethinking how a contemporary art museum can visually communicate experimentation, openness, and cultural dialogue. The idea was to create a flexible identity system that reflects the dynamic nature of contemporary art. The acronym MACS becomes the central graphic element, working as both a logo and a modular structure that adapts across exhibitions, artists, and visual applications. Minimalist compositions and bold typography create a clean framework where art remains the protagonist. This is a personal creative exploration on how branding can evolve with contemporary culture.

Cover image for A personal art direction and

A personal art direction and graphic design study inspired by the football club Corinthians. Concept: “Cidade Cinza” The idea explores the symbolism behind black and white — the club’s iconic colors — blending into grey as a metaphor for unity. Just like a city where different stories, cultures, and people coexist, the project connects the team’s visual identity with the diversity of its supporters. Through bold typography, compositions, and the fusion of black and white elements, the visual language creates a “grey city” where differences merge into collective strength. This is a personal creative exploration of how graphic design and art direction can translate identity, city culture, and unity through the symbolism of color.
