Traditional paper marbling can produce beautiful patterns, but it also requires paint, water, trays, paper, and a workspace you do not mind getting messy.

Here’s a Cool Tip: Create colorful marbled artwork without making a mess.

Paint Toys Marbling recreates the most satisfying parts of that process inside a web browser. 

You add drops of virtual ink to a simulated water surface and then pull a comb through the colors to form waves, feathers, curls, and flowing bands.

There is no complicated toolbar to learn. The intentionally simple interface encourages you to click, drag, experiment, clear the canvas, and try again.

Not every worthwhile iPhone update changes the Home Screen or adds a feature you can immediately try.

Some updates work quietly in the background, repairing security weaknesses, fixing software problems, and preparing your device for what comes next. 

That is exactly what Apple is doing with iOS 26.6.

Here’s a Cool Tip: Update to iOS 26.6 Now to Protect Your iPhone and Prepare Spotlight for iOS 27.

iOS 26.6 includes bug fixes, security updates, and an optimization of the Spotlight index in preparation for iOS 27.

Windows 11 Screen Tint Makes Bright Screens Easier on the Eyes

Windows 11 Screen Tint Makes Bright Screens Easier on the Eyes

Bright screens are not always a brightness problem. Sometimes the intensity of modern apps, websites, and documents is what leaves your eyes feeling tired after a long day.

Windows 11's new Screen Tint accessibility feature offers another way to improve screen comfort by applying a customizable color overlay across the entire display. Availability may vary depending on your Windows version and rollout status.

After eight hours of email, spreadsheets, Teams meetings, web browsing, and document editing, many people reach for the brightness controls. 

The problem is that brightness is not always what's causing the discomfort.

Here's a Cool Tip: Customize your screen's comfort level with Screen Tint.

Microsoft's new Screen Tint feature for Windows 11 takes a different approach. Instead of simply dimming the display, it adds a customizable color overlay designed to make bright screens feel less visually intense during long work sessions. 

The feature is intended to help users who experience eye fatigue, light sensitivity, or general visual discomfort from bright displays.

Screen Tint joins other Windows accessibility tools designed to make computing more comfortable, but it fills a unique gap between Night Light and Color Filters.

Getting locked out of a primary digital account can stall an entire workday or disrupt personal travel plans. 

Passwords can be forgotten, smartphones can be misplaced during travel, and secondary authentication hardware isn't always within reach. 

Here’s a Cool Tip: Set up Google selfie Video Verification.

Google recently introduced a modern backup option designed to resolve account access emergencies: selfie video verification.

This backup mechanism provides a secure alternative when primary devices, passkeys, or recovery codes aren't available. 

Rather than relying solely on static phone numbers or secondary email addresses, users can record a short video of their face while moving their head in guided directions.

Managing repetitive digital administrative tasks eats away at productive hours every week. 

Tracking down action items from email threads, summarizing meeting notes, and updating spreadsheets manually drains focus from creative or strategic work.

Here’s a Cool Tip: Put Gemini Spark to work on recurring background tasks.  Access is now expanding to AI Pro and Ultra users. 

Google launched Gemini Spark to tackle this persistent friction. 

Spark acts as a personal AI agent that runs continuously in the cloud, carrying out background workflows even when your computer is closed or your smartphone is locked. 

As Google broadens access to this background assistant, automating daily work routines becomes far more practical for everyday users.

How to Organize Your Web Browser with Chrome Vertical Tabs

How to Organize Your Web Browser with Chrome Vertical Tabs

Google Chrome now lets you arrange open tabs along the side of your screen instead of crowding them across the top. Moving your tabs vertically keeps full page titles visible and helps you manage large research projects without losing your place.

Opening dozens of browser tabs during a busy workday used to turn your tab bar into a row of tiny, unreadable icons. 

Squinting at tiny favicons to figure out which page holds your spreadsheet or research document drains focus and slows down your momentum. 

Modern widescreen monitors offer plenty of side-to-side space, yet traditional browser layouts compress tabs horizontally until the title text disappears completely.

Here’s a Cool Tip: Switch Chrome to Vertical Tabs.

Google introduced native vertical tabs to help solve this daily workspace clutter. 

By shifting your tab layout to a vertical column on the side of your window, you can read full page titles, organize tab groups, and reclaim vertical screen space for reading websites.

Keeping track of multiple document versions while researching often leads to frustrating mistakes. 

You might outline a project in a Google Doc, upload it to your AI assistant for analysis, and then make further edits to the original file. 

In the past, those edits meant you had to manually delete the old file from your workspace and upload the new one just to ask questions about your latest changes.

Here is a Cool Tip: Connect your Google Drive documents to Gemini Notebook for automatic updates.

In May 2026, the company added automatic Google Drive syncing to the tool. 

Then, on July 16, 2026, Google officially renamed NotebookLM to Gemini Notebook. 

This rebrand brings the tool deeper into the Google ecosystem. 

The combination of a new identity and background syncing makes the research process much faster.

Instead of selecting a standard brush, you drag an animated octopus or squid across the screen. 

These characters bring the canvas to life with realistic fluid physics, synthesizing sounds as you create.

Most PCs connect audio to a single Bluetooth device at a time, leaving users searching for splitters, adapters, or awkward workarounds.

Microsoft recently released an update with Shared Audio, a Windows 11 feature designed for compatible devices that support Bluetooth LE Audio. 

The feature allows users to broadcast the same audio stream to two supported listening devices from a single PC.

For people who frequently share videos, music, presentations, or training content, it offers a more convenient way to listen together without additional accessories.
